+## Introduction
+
+To work with platforms based on blockchain technology, in particular with Ethereum-like blockchains, developer must be fluent in concepts such as a crypto wallet, private and public key, smart contract, token and others. We will use these concepts without explaining their meanings. For more information about Ethereum, we recommend reading the book [Mastering Ethereum](https://github.com/ethereumbook/ethereumbook), by Andreas M. Antonopoulos and Gavin Wood.
+
+**To create keystore we forced our users to use some password, which will be used in some operations, like transactions sending. We believe that security is important for such operations and this increases its level. You are free to use a pre-compiled password in your code, that is not set by the keystore user, at your own risk.**
+
+*In code examples we used force-unwrapped Swift optionals for better readability of example code. We recommend that you do not use this method to get rid of optional values.*
+
+### Preffered models
+
+To describe the library's capabilities, we will use the models described below, however you can use the models that are convenient for you.
+

-### Manage Keystore
-
-#### Save keystore to the memory
+### Get Keystore Manager from wallet data
 
 ```swift
-//First you need a `KeystoreManager` instance:
-guard let userDirectory = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first,
-      let keystoreManager = KeystoreManager.managerForPath(userDirectory + "/keystore")
-      else {
-    fatalError("Couldn't create a KeystoreManager.")
-}
-
-// Next you create a new Keystore:
-
-let newKeystore = try? EthereumKeystoreV3(password: "YOUR_PASSWORD")
-
-// Then you save the created keystore to the file system:
-
-let newKeystoreJSON = try? JSONEncoder().encode(newKeystore.keystoreParams)
-FileManager.default.createFile(atPath: "\(keystoreManager.path)/keystore.json", contents: newKeystoreJSON, attributes: nil)
-
-// Later you can retreive it:
-
-if let address = keystoreManager.addresses?.first,
-let retrievedKeystore = keystoreManager.walletForAddress(address) as? EthereumKeystoreV3 {
-    return retrievedKeystore
+let data = wallet.data
+let keystoreManager: KeystoreManager
+if wallet.isHD {

+	keystoreManager = KeystoreManager([keystore])
+} else {
+	let keystore = EthereumKeystoreV3(data)!
+	keystoreManager = KeystoreManager([keystore])
 }
 ```
 
-#### Get Keysore Manager
+### Get wallet Private key
 
 ```swift
-// 1st - Get wallet, that is saved in some storage
+let password = "web3swift"
+let ethereumAddress = EthereumAddress(wallet.address)!
+let pkData = try! keysoreManager.UNSAFE_getPrivateKeyData(password: password, account: ethereumAddress).toHexString()
+```
 
-func getWalletFromStorage() throws -> WalletModel {

+### web3 instance
 
-#### Get wallet private key
+Firstly you need to initialize 'web3' instance for almost all further operations:
+```swift
+// common Http/Https provider
+let endpoint = "https://some.endpoint"
+let web3 = web3(provider: Web3HttpProvider(URL(string: endpoint)!)!)
+// precompiled Infura providers
+let web3 = Web3.InfuraMainnetWeb3() // Mainnet Infura Endpoint Provider
+let web3 = Web3.InfuraRinkebyWeb3() // Rinkeby Infura Endpoint Provider
+let web3 = Web3.InfuraRopstenWeb3() // Ropsten Infura Endpoint Provider
+```
 
+Then you will need to attach keystore manager to web3 instance:
 ```swift
-func getPrivateKey(for wallet: WalletModel, password: String) throws -> String {
-	do {
-		guard let ethereumAddress = EthereumAddress(wallet.address) else {
-			throw Web3Error.walletError
-		}
-		guard let manager = try? keystoreManager() else {
-			throw Web3Error.keystoreError(err: .invalidAccountError)
-		}
-		let pkData = try manager.UNSAFE_getPrivateKeyData(password: password, account: ethereumAddress)
-		return pkData.toHexString()
-	} catch let error {

-## Chain state
+## Websockets
 
-### Get Block number
+### Web3socketDelegate
 
+To receive messages from endpoint you need to create a class that adopt to Web3SocketDelegate protocol.
+Later, in order to open a connection to WebSocket server, you will use socket provider (WebsocketProvider or InfuraWebsocketProvider). And we recommend you to make it a property, so it doesn't get deallocated right after being setup.
 ```swift
-func getBlockNumber(_ web3: web3) throws -> BigUInt {
-    do {
-		let blockNumber = try web3.eth.getBlockNumber()
-		return blockNumber
-    } catch let error {
-		throw error 
-    }
+class DelegateClass: Web3SocketDelegate {
+	var socketProvider: WebsocketProvider? = nil // WebSocket Provider
+	var socketProvider: InfuraWebsocketProvider? = nil // Infura WebSocket Provider
+	
+	// Protocol method, here will be messages, received from WebSocket server
+	func received(message: Any) {
+        	// Make something with message
+    	}
 }
+``` 
+
+### Custom Websocket Provider
+
+#### Connect to custom endpoint
+
+You can create WebsocketProvider and connect/disconnect it.
+```swift
+socketProvider = WebsocketProvider("ws://your.endpoint", delegate: delegate)
+socketProvider.connectSocket()
+/// Some code
+/// ...
+socketProvider.disconnectSocket()
+``` 
+
+Or you can create already connected WebsocketProvider
+```swift
+socketProvider = WebsocketProvider.connectToSocket("ws://your.endpoint", delegate: delegate)
+```
+
+#### Send message 
+
+```swift
+// String message
+socketProvider.writeMessage(String()) 
+// Data message
+socketProvider.writeMessage(Data())
+```
+
+### Infura Websocket Provider
+
+#### Connect to Infura endpoint 
+
+```swift
+socketProvider = InfuraWebsocketProvider.connectToInfuraSocket(.Mainnet, delegate: delegate)
+```
+
+#### Connect to custom endpoint with API similar to Infura WSS endpoint
+
+```swift
+socketProvider = InfuraWebsocketProvider.connectToSocket("ws://your.endpoint", delegate: delegate)
 ```
+
+#### Create a filter in the node to notify when something happened
+
+To study possible filters read [Infura WSS filters documentation](https://infura.io/docs/ethereum/wss/introduction)
+
+```swift
+try! socketProvider.filter(method: <InfuraWebsocketMethod>, params: <[Encodable]?>)
+```
+
+####  Get new pending transactions
+
+```swift
+try! socketProvider.filter(method: .newPendingTransactionFilter)
+```
+
+#### Create a new subscription over particular events
+
+To study possible subscriptions read [Infura WSS subscriptions documentation](https://infura.io/docs/ethereum/wss/eth_subscribe)
+
+```swift
+try! socketProvider.subscribe(params: <[Encodable]>)
+```
+
+#### Subscribe on new pending transactions
+
+```swift
+try! socketProvider.subscribeOnNewPendingTransactions()
+```

+
+Starscream is a conforming WebSocket ([RFC 6455](http://tools.ietf.org/html/rfc6455)) client library in Swift.
+
+Its Objective-C counterpart can be found here: [Jetfire](https://github.com/acmacalister/jetfire)
+
+## Features
+
+- Conforms to all of the base [Autobahn test suite](http://autobahn.ws/testsuite/).
+- Nonblocking. Everything happens in the background, thanks to GCD.
+- TLS/WSS support.
+- Compression Extensions support ([RFC 7692](https://tools.ietf.org/html/rfc7692))
+- Simple concise codebase at just a few hundred LOC.
+
+## Example
+
+First thing is to import the framework. See the Installation instructions on how to add the framework to your project.
+
+```swift
+import Starscream
+```
+
+Once imported, you can open a connection to your WebSocket server. Note that `socket` is probably best as a property, so it doesn't get deallocated right after being setup.
+
+```swift
+socket = WebSocket(url: URL(string: "ws://localhost:8080/")!)
+socket.delegate = self
+socket.connect()
+```
+
+After you are connected, there are some delegate methods that we need to implement.
+
+### websocketDidConnect
+
+websocketDidConnect is called as soon as the client connects to the server.
+
+```swift
+func websocketDidConnect(socket: WebSocketClient) {
+    print("websocket is connected")
+}
+```
+
+### websocketDidDisconnect
+
+websocketDidDisconnect is called as soon as the client is disconnected from the server.
+
+```swift
+func websocketDidDisconnect(socket: WebSocketClient, error: Error?) {
+	print("websocket is disconnected: \(error?.localizedDescription)")
+}
+```
+
+### websocketDidReceiveMessage
+
+websocketDidReceiveMessage is called when the client gets a text frame from the connection.
+
+```swift
+func websocketDidReceiveMessage(socket: WebSocketClient, text: String) {
+	print("got some text: \(text)")
+}
+```
+
+### websocketDidReceiveData
+
+websocketDidReceiveData is called when the client gets a binary frame from the connection.
+
+```swift
+func websocketDidReceiveData(socket: WebSocketClient, data: Data) {
+	print("got some data: \(data.count)")
+}
+```
+
+### Optional: websocketDidReceivePong *(required protocol: WebSocketPongDelegate)*
+
+websocketDidReceivePong is called when the client gets a pong response from the connection. You need to implement the WebSocketPongDelegate protocol and set an additional delegate, eg: ` socket.pongDelegate = self`
+
+```swift
+func websocketDidReceivePong(socket: WebSocketClient, data: Data?) {
+	print("Got pong! Maybe some data: \(data?.count)")
+}
+```
+
+Or you can use closures.
+
+```swift
+socket = WebSocket(url: URL(string: "ws://localhost:8080/")!)
+//websocketDidConnect
+socket.onConnect = {
+    print("websocket is connected")
+}
+//websocketDidDisconnect
+socket.onDisconnect = { (error: Error?) in
+    print("websocket is disconnected: \(error?.localizedDescription)")
+}
+//websocketDidReceiveMessage
+socket.onText = { (text: String) in
+    print("got some text: \(text)")
+}
+//websocketDidReceiveData
+socket.onData = { (data: Data) in
+    print("got some data: \(data.count)")
+}
+//you could do onPong as well.
+socket.connect()
+```
+
+One more: you can listen to socket connection and disconnection via notifications. Starscream posts `WebsocketDidConnectNotification` and `WebsocketDidDisconnectNotification`. You can find an `Error` that caused the disconection by accessing `WebsocketDisconnectionErrorKeyName` on notification `userInfo`.
+
+
+## The delegate methods give you a simple way to handle data from the server, but how do you send data?
+
+### write a binary frame
+
+The writeData method gives you a simple way to send `Data` (binary) data to the server.
+
+```swift
+socket.write(data: data) //write some Data over the socket!
+```
+
+### write a string frame
+
+The writeString method is the same as writeData, but sends text/string.
+
+```swift
+socket.write(string: "Hi Server!") //example on how to write text over the socket!
+```
+
+### write a ping frame
+
+The writePing method is the same as write, but sends a ping control frame.
+
+```swift
+socket.write(ping: Data()) //example on how to write a ping control frame over the socket!
+```
+
+### write a pong frame
+
+
+the writePong method is the same as writePing, but sends a pong control frame.
+
+```swift
+socket.write(pong: Data()) //example on how to write a pong control frame over the socket!
+```
+
+Starscream will automatically respond to incoming `ping` control frames so you do not need to manually send `pong`s.
+
+However if for some reason you need to control this process you can turn off the automatic `ping` response by disabling `respondToPingWithPong`.
+
+```swift
+socket.respondToPingWithPong = false //Do not automaticaly respond to incoming pings with pongs.
+```
+
+In most cases you will not need to do this.
+
+### disconnect
+
+The disconnect method does what you would expect and closes the socket.
+
+```swift
+socket.disconnect()
+```
+
+The socket can be forcefully closed, by specifying a timeout (in milliseconds). A timeout of zero will also close the socket immediately without waiting on the server.
+
+```swift
+socket.disconnect(forceTimeout: 10, closeCode: CloseCode.normal.rawValue)
+```
+
+### isConnected
+
+Returns if the socket is connected or not.
+
+```swift
+if socket.isConnected {
+  // do cool stuff.
+}
+```
+
+### Custom Headers
+
+You can also override the default websocket headers with your own custom ones like so:
+
+```swift
+var request = URLRequest(url: URL(string: "ws://localhost:8080/")!)
+request.timeoutInterval = 5
+request.setValue("someother protocols", forHTTPHeaderField: "Sec-WebSocket-Protocol")
+request.setValue("14", forHTTPHeaderField: "Sec-WebSocket-Version")
+request.setValue("Everything is Awesome!", forHTTPHeaderField: "My-Awesome-Header")
+let socket = WebSocket(request: request)
+```
+
+### Custom HTTP Method
+
+Your server may use a different HTTP method when connecting to the websocket:
+
+```swift
+var request = URLRequest(url: URL(string: "ws://localhost:8080/")!)
+request.httpMethod = "POST"
+request.timeoutInterval = 5
+let socket = WebSocket(request: request)
+```
+
+### Protocols
+
+If you need to specify a protocol, simple add it to the init:
+
+```swift
+//chat and superchat are the example protocols here
+socket = WebSocket(url: URL(string: "ws://localhost:8080/")!, protocols: ["chat","superchat"])
+socket.delegate = self
+socket.connect()
+```
+
+### Self Signed SSL
+
+```swift
+socket = WebSocket(url: URL(string: "ws://localhost:8080/")!, protocols: ["chat","superchat"])
+
+//set this if you want to ignore SSL cert validation, so a self signed SSL certificate can be used.
+socket.disableSSLCertValidation = true
+```
+
+### SSL Pinning
+
+SSL Pinning is also supported in Starscream.
+
+```swift
+socket = WebSocket(url: URL(string: "ws://localhost:8080/")!, protocols: ["chat","superchat"])
+let data = ... //load your certificate from disk
+socket.security = SSLSecurity(certs: [SSLCert(data: data)], usePublicKeys: true)
+//socket.security = SSLSecurity() //uses the .cer files in your app's bundle
+```
+You load either a `Data` blob of your certificate or you can use a `SecKeyRef` if you have a public key you want to use. The `usePublicKeys` bool is whether to use the certificates for validation or the public keys. The public keys will be extracted from the certificates automatically if `usePublicKeys` is choosen.
+
+### SSL Cipher Suites
+
+To use an SSL encrypted connection, you need to tell Starscream about the cipher suites your server supports. 
+
+```swift
+socket = WebSocket(url: URL(string: "wss://localhost:8080/")!, protocols: ["chat","superchat"])
+
+// Set enabled cipher suites to AES 256 and AES 128
+socket.enabledSSLCipherSuites = [TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256] 
+```
+
+If you don't know which cipher suites are supported by your server, you can try pointing [SSL Labs](https://www.ssllabs.com/ssltest/) at it and checking the results.
+
+### Compression Extensions
+
+Compression Extensions ([RFC 7692](https://tools.ietf.org/html/rfc7692)) is supported in Starscream.  Compression is enabled by default, however compression will only be used if it is supported by the server as well.  You may enable or disable compression via the `.enableCompression` property:
+
+```swift
+socket = WebSocket(url: URL(string: "ws://localhost:8080/")!)
+socket.enableCompression = false
+```
+
+Compression should be disabled if your application is transmitting already-compressed, random, or other uncompressable data.
+
+### Custom Queue
+
+A custom queue can be specified when delegate methods are called. By default `DispatchQueue.main` is used, thus making all delegate methods calls run on the main thread. It is important to note that all WebSocket processing is done on a background thread, only the delegate method calls are changed when modifying the queue. The actual processing is always on a background thread and will not pause your app.
+
+```swift
+socket = WebSocket(url: URL(string: "ws://localhost:8080/")!, protocols: ["chat","superchat"])
+//create a custom queue
+socket.callbackQueue = DispatchQueue(label: "com.vluxe.starscream.myapp")
+```
+
+## Example Project
+
+Check out the SimpleTest project in the examples directory to see how to setup a simple connection to a WebSocket server.
+
+## Requirements
+
+Starscream works with iOS 7/OSX 10.9 or above. It is recommended to use iOS 8/10.10 or above for CocoaPods/framework support. To use Starscream with a project targeting iOS 7, you must include all Swift files directly in your project.
+
+## Installation
+
+### CocoaPods
+
+Check out [Get Started](http://cocoapods.org/) tab on [cocoapods.org](http://cocoapods.org/).
+
+To use Starscream in your project add the following 'Podfile' to your project
+
+	source 'https://github.com/CocoaPods/Specs.git'
+	platform :ios, '9.0'
+	use_frameworks!
+
+	pod 'Starscream', '~> 3.0.2'
+
+Then run:
+
+    pod install
+
+### Carthage
+
+Check out the [Carthage](https://github.com/Carthage/Carthage) docs on how to add a install. The `Starscream` framework is already setup with shared schemes.
+
+[Carthage Install](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application)
+
+You can install Carthage with [Homebrew](http://brew.sh/) using the following command:
+
+```bash
+$ brew update
+$ brew install carthage
+```
+
+To integrate Starscream into your Xcode project using Carthage, specify it in your `Cartfile`:
+
+```
+github "daltoniam/Starscream" >= 3.0.2
+```
+
+### Rogue
+
+First see the [installation docs](https://github.com/acmacalister/Rogue) for how to install Rogue.
+
+To install Starscream run the command below in the directory you created the rogue file.
+
+```
+rogue add https://github.com/daltoniam/Starscream
+```
+
+Next open the `libs` folder and add the `Starscream.xcodeproj` to your Xcode project. Once that is complete, in your "Build Phases" add the `Starscream.framework` to your "Link Binary with Libraries" phase. Make sure to add the `libs` folder to your `.gitignore` file.
+
+### Swift Package Manager
+
+The [Swift Package Manager](https://swift.org/package-manager/) is a tool for automating the distribution of Swift code and is integrated into the `swift` compiler.
+
+Once you have your Swift package set up, adding Starscream as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.
+
+```swift
+dependencies: [
+    .Package(url: "https://github.com/daltoniam/Starscream.git", majorVersion: 3)
+]
+```
+
+### Other
+
+Simply grab the framework (either via git submodule or another package manager).
+
+Add the `Starscream.xcodeproj` to your Xcode project. Once that is complete, in your "Build Phases" add the `Starscream.framework` to your "Link Binary with Libraries" phase.
+
+### Add Copy Frameworks Phase
+
+If you are running this in an OSX app or on a physical iOS device you will need to make sure you add the `Starscream.framework` to be included in your app bundle. To do this, in Xcode, navigate to the target configuration window by clicking on the blue project icon, and selecting the application target under the "Targets" heading in the sidebar. In the tab bar at the top of that window, open the "Build Phases" panel. Expand the "Link Binary with Libraries" group, and add `Starscream.framework`. Click on the + button at the top left of the panel and select "New Copy Files Phase". Rename this new phase to "Copy Frameworks", set the "Destination" to "Frameworks", and add `Starscream.framework` respectively.
+
+
+## WebSocketAdvancedDelegate
+The advanced delegate acts just like the simpler delegate but provides some additional information on the connection and incoming frames.
+
+```swift
+socket.advancedDelegate = self
+```
+
+In most cases you do not need the extra info and should use the normal delegate.
+
+#### websocketDidReceiveMessage
+```swift
+func websocketDidReceiveMessage(socket: WebSocketClient, text: String, response: WebSocket.WSResponse) {
+	print("got some text: \(text)")
+	print("First frame for this message arrived on \(response.firstFrame)")
+}
+```
+
+#### websocketDidReceiveData
+```swift
+func websocketDidReceiveData(socket: WebSocketClient, data: Date, response: WebSocket.WSResponse) {
+	print("got some data it long: \(data.count)")
+	print("A total of \(response.frameCount) frames were used to send this data")
+}
+```
+
+#### websocketHttpUpgrade
+These methods are called when the HTTP upgrade request is sent and when the response returns.
+```swift
+func  websocketHttpUpgrade(socket: WebSocketClient, request: CFHTTPMessage) {
+	print("the http request was sent we can check the raw http if we need to")
+}
+```
+
+```swift
+func  websocketHttpUpgrade(socket: WebSocketClient, response: CFHTTPMessage) {
+	print("the http response has returned.")
+}
+```
+
+## KNOWN ISSUES
+- WatchOS does not have the the CFNetwork String constants to modify the stream's SSL behavior. It will be the default Foundation SSL behavior. This means watchOS CANNOT use `SSLCiphers`,  `disableSSLCertValidation`, or SSL pinning. All these values set on watchOS will do nothing. 
+- Linux does not have the security framework, so it CANNOT use SSL pinning or `SSLCiphers` either. 
+
+
+## TODOs
+
+- [ ] Add Unit Tests - Local WebSocket server that runs against Autobahn

+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.</string>

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.</string>
