+# Loom Truffle Provider
+
+Adapter that allows Truffle Suite to communicate with Loom DappChain
+
+## Install
+
+```bash
+yarn add loom-truffle-provider
+# or
+npm install loom-truffle-provider
+```
+
+## Requirements
+
+```
+Node >= 8
+```
+
+## Truffle
+
+Download and install [Truffle](https://github.com/trufflesuite/truffle)
+
+## Description
+
+Loom Truffle Provider allows to deploy smart contracts written on Solidity on Loom DappChain extending the Truffle use to Loom DappChain also. The following configuration is an example written on `truffle.js` (Truffle configuration)
+
+```javascript
+const { readFileSync } = require('fs')
+const TruffleLoomAdapter = require('truffle-loom-provider')
+
+const chainId    = 'default'
+const writeUrl   = 'ws://127.0.0.1:46657/websocket'
+const readUrl    = 'ws://127.0.0.1:9999/queryws'
+const privateKey = readFileSync('./privateKey', 'utf-8')
+
+const truffleLoomAdapter = new TruffleLoomAdapter(chainId, writeUrl, readUrl, privateKey)
+
+module.exports = {
+  networks: {
+    loomdappchain: {
+      provider: function() {
+        return truffleLoomAdapter
+      }, network_id: '*'
+    }
+  }
+};
+```
+
+## Notes
+
+* Make sure to have the Loom DappChain running before Truffle commands
+* The configuration up above requires the Truffle network option (ex.: `truffle deploy --network loomdappchain`)
