+# Using Pantheon with Truffle 
+
+Developing for Pantheon using Truffle is the same as using Truffle to develop for the public Ethereum networks. 
+Truffle supports Pantheon with the only difference being Pantheon does not implement private key management. 
+To use Pantheon with Truffle, you must configure a Truffle wallet.
+
+## Install Truffle Wallet 
+
+To install the Truffle wallet:
+
+```bash
+npm install --save truffle-hdwallet-provider@web3-one
+```
+
+!!!note
+    With Truffle 5, you must use a Web3 1.0 enabled wallet or the Truffle tasks hang.
+
+#### Modify the Truffle Configuration File 
+
+Modify the `truffle-config.js` file in the project directory to add the wallet provider. Replace: 
+
+* `<JSON-RPC-http-endpoint>` with the JSON-RPC endpoint (IP address and port) of a Pantheon node
+*  `<account-private-key>` with the private key of an Ethereum account containing Ether 
+
+```javascript
+const PrivateKeyProvider = require("truffle-hdwallet-provider");
+const privateKey = "<account-private-key>";
+const privateKeyProvider = new PrivateKeyProvider(privateKey, "<JSON-RPC-http-endpoint>");
+
+module.exports = {
+  // See <http://truffleframework.com/docs/advanced/configuration>
+  // for more about customizing your Truffle configuration!
+  networks: {
+    pantheonWallet: {
+      provider: privateKeyProvider,
+      network_id: "*"
+    },
+  }
+};
+```
+
+### Start Pantheon Node 
+
+Start a Pantheon node with JSON-RPC enabled on the endpoint specified in the Truffle configuration 
+file.  
+
+### Deploy Contract 
+
+To deploy a contract onto the Pantheon network: 
+
+```bash
+truffle migrate --network pantheonWallet
+```
+
