-NEO 3.0 (under development): A distributed network for the Smart Economy
-================
-
-NEO uses digital identity and blockchain technology to digitize assets and leverages smart contracts for autonomously managed digital assets to create a "smart economy" within a decentralized network.
-
-To learn more about NEO, please read the [White Paper](https://docs.neo.org/en-us/whitepaper.html)|[白皮书](https://docs.neo.org/zh-cn/whitepaper.html).
-
-NEO 2.x: Reference template  
-================
-
-NEO adopts a model of continuous improvement and evolution.
-We believe that the research and development of blockchain technology will be kept in continuous transformation for the next years.
-From 2017 until the middle of 2020 (estimated), NEO 2.x will still be supported and the compatibility of new packages will be maintained.
-
-A link to the essential C# reference implementation can be seen below:
-
-* [neo](https://github.com/neo-project/neo/tree/master-2.x): core implementation (branch `master-2.x`)
-* [neo-vm](https://github.com/neo-project/neo-vm/tree/master-2.x): virtual machine (branch `master-2.x`)
-* [neo-cli](https://github.com/neo-project/neo-cli/tree/master-2.x): command-line interface (branch `master-2.x`)
-* [neo-plugins](https://github.com/neo-project/neo-plugins/tree/master-2.x): plugins (branch `master-2.x`)
-* [neo-devpack-dotnet](https://github.com/neo-project/neo-devpack-dotnet/tree/master-2.x): NeoContract compiler and development pack for .NET (branch `master-2.x`)
-
-NEO 1.x was known as Antshares and the roots of the code can be found historically in this current repository.
-

+3. [Related projects](#related-projects)
+4. [Opening a new issue](#opening-a-new-issue)  
+5. [Bounty program](#bounty-program)
+6. [License](#license)
 
-If you need to develop on Linux or macOS, just install the [.NET Core SDK](https://www.microsoft.com/net/core).
+## Overview
+This repository contain main classes of the 
+[Neo](https://www.neo.org) blockchain.   
+Visit the [documentation](https://docs.neo.org/docs/en-us/index.html) to get started.
 
-To install Neo SDK to your project, run the following command in the [Package Manager Console](https://docs.nuget.org/ndocs/tools/package-manager-console):
 
-```
-PM> Install-Package Neo
-```
+*Note: This is Neo 3 branch, currently under development. For the current stable version, please [click here](https://github.com/neo-project/neo/tree/master-2.x)*
 
-For more information about how to build DAPPs for NEO, please read the [documentation](http://docs.neo.org/en-us/sc/introduction.html)|[文档](http://docs.neo.org/zh-cn/sc/introduction.html).
 
-Daily builds
---------
 
-If you want to use the [latest daily build](https://www.myget.org/feed/neo/package/nuget/Neo) then you need to add a NuGet.Config to your app with the following content:
+## Project structure
+An overview of the project folders can be seen below.

+|Folder|Content|
+|---|---|
+|Consensus| Classes used in the dBFT consensus algorithm, including the `ConsensusService` actor.|
+|Cryptography|General cryptography classes including ECC implementation.|
+|IO|Data structures used for caching and collection interaction.|
+|Ledger|Classes responsible for the state control, including the `MemoryPool` and `Blockchain` classes.|
+|Network|Peer-to-peer protocol implementation classes.|
+|Persistence|Classes used to allow other classes to access application state.|
+|Plugins|Interfaces used to extend Neo, including the storage interface.|
+|SmartContract|Native contracts, `ApplicationEngine`, `InteropService` and other smart-contract related classes.|
+|VM|Helper methods used to interact with the VM.|
+|Wallet|Wallet and account implementation. |
 
-*NOTE: This NuGet.Config should be with your application unless you want nightly packages to potentially start being restored for other apps on the machine.*
 
-How to Contribute
---------
+## Related projects
+Code references are provided for all platform building blocks. That includes the base library, the VM, a command line application and the compiler. 
 
-You can contribute to NEO with [issues](https://github.com/neo-project/neo/issues) and [PRs](https://github.com/neo-project/neo/pulls). Simply filing issues for problems you encounter is a great way to contribute. Contributing implementations is greatly appreciated.
+* [**neo:**](https://github.com/neo-project/neo/tree/) Neo core library, contains base classes, including ledger, p2p and IO modules.
+* [neo-vm:](https://github.com/neo-project/neo-vm/) Neo Virtual Machine is a decoupled VM that Neo uses to execute its scripts. It also uses the `InteropService` layer to extend its functionalities.
+* [neo-node:](https://github.com/neo-project/neo-node/) Executable version of the Neo library, exposing features using a command line application or GUI.
+* [neo-modules:](https://github.com/neo-project/neo-modules/) Neo modules include additional tools and plugins to be used with Neo.
+* [neo-devpack-dotnet:](https://github.com/neo-project/neo-devpack-dotnet/) These are the official tools used to convert a C# smart-contract into a *neo executable file*.
 
-We use and recommend the following workflow:
+## Opening a new issue
+Please feel free to create new issues to suggest features or ask questions.
 
-1. Create an issue for your work.
-    * You can skip this step for trivial changes.
-	* Reuse an existing issue on the topic, if there is one.
-	* Clearly state that you are going to take on implementing it, if that's the case. You can request that the issue be assigned to you. Note: The issue filer and the implementer don't have to be the same person.
-1. Create a personal fork of the repository on GitHub (if you don't already have one).
-1. Create a branch off of master(`git checkout -b mybranch`).
-    * Name the branch so that it clearly communicates your intentions, such as issue-123 or githubhandle-issue.
-	* Branches are useful since they isolate your changes from incoming changes from upstream. They also enable you to create multiple PRs from the same fork.
-1. Make and commit your changes.
-1. Add new tests corresponding to your change, if applicable.
-1. Build the repository with your changes.
-    * Make sure that the builds are clean.
-	* Make sure that the tests are all passing, including your new tests.
-1. Create a pull request (PR) against the upstream repository's master branch.
-    * Push your changes to your fork on GitHub.
