+Znode Build Instructions and Notes
+=============================
+ - Version 0.1.5
+ - Date: 28 November 2017
+
+Prerequisites
+-------------
+ - Ubuntu 16.04+
+ - Libraries to build from zcoin source
+ - Port **18618** is open
+
+Step 1. Build
+----------------------
+**1.1.**  Check out from source:
+
+    git clone -b znode https://github.com/zcoinofficial/zcoin
+
+**1.2.**  See [README.md](README.md) for instructions on building.
+
+Step 2. (Optional - only if firewall is running). Open port 18618
+----------------------
+**2.1.**  Run:
+
+    sudo ufw allow 18618
+    sudo ufw default allow outgoing
+    sudo ufw enable
+
+Step 3. First run on your Local Wallet
+----------------------
+**3.0.**  Go to the checked out folder
+
+    cd zcoin
+
+**3.1.**  Start daemon in testnet mode:
+
+    ./src/zcoind -daemon -server -testnet
+
+**3.2.**  Generate znodeprivkey:
+
+    ./src/zcoin-cli znode genkey
+
+(Store this key)
+
+**3.3.**  Get wallet address:
+
+    ./src/zcoin-cli getaccountaddress 0
+
+**3.4.**  Send to received address **exactly 1000 XZC** in **1 transaction**. Wait for 15 confirmations.
+
+**3.5.**  Stop daemon:
+
+    ./src/zcoin-cli stop
+
+Step 4. In your VPS where you are hosting your Znode. Update config files
+----------------------
+**4.1.**  Create file **zcoin.conf** (in folder **~/.zcoin**)
+
+    rpcuser=username
+    rpcpassword=password
+    rpcallowip=127.0.0.1
+    testnet=1
+    debug=1
+    txindex=1
+    daemon=1
+    server=1
+    listen=1
+    maxconnections=24
+    znode=1
+    znodeprivkey=XXXXXXXXXXXXXXXXX  ## Replace with your znode private key
+    externalIP=XXX.XXX.XXX.XXX ## Replace with your node external IP
+
+**4.2.**  Create file **znode.conf** (in 2 folders **~/.zcoin** and **~/.zcoin/testnet3**) contains the following info:
+ - LABEL: A one word name you make up to call your node (ex. ZN1)
+ - IP:PORT: Your znode VPS's IP, and the port is always 18168.
+ - ZNODEPRIVKEY: This is the result of your "znode genkey" from earlier.
+ - TRANSACTION HASH: The collateral tx. hash from the 1000 XZC deposit.
+ - INDEX: The Index is always 0 or 1.
+
+To get TRANSACTION HASH, run:
+
+    ./src/zcoin-cli znode outputs
+
+The output will look like:
+
+    { "d6fd38868bb8f9958e34d5155437d009b72dfd33fc28874c87fd42e51c0f74fdb" : "0", }
+
+Sample of znode.conf:
+
+    ZN1 51.52.53.54:18168 XrxSr3fXpX3dZcU7CoiFuFWqeHYw83r28btCFfIHqf6zkMp1PZ4 d6fd38868bb8f9958e34d5155437d009b72dfd33fc28874c87fd42e51c0f74fdb 0
+
+Step 5. Run a znode
+----------------------
+**5.1.**  Start znode:
+
+    ./src/zcoin-cli znode start-alias <LABEL>
+
+For example:
+
+    ./src/zcoin-cli znode start-alias ZN1
+
+**5.2.**  To check node status:
+
+    ./src/zcoin-cli znode debug
+
+If not successfully started, just repeat start command
