 # Ethereum JavaScript API
 
 This is the Ethereum compatible JavaScript API using `Promise`s
-which implements the [Generic JSON RPC](https://github.com/ethereum/wiki/wiki/Generic-JSON-RPC) spec.
+which implements the [Generic JSON RPC](https://github.com/ethereum/wiki/wiki/Generic-JSON-RPC) spec. It's available on npm as a node module and also for bower and component as an embeddable js
 
-For an example see `index.html`.
+[![NPM version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![dependency status][dep-image]][dep-url] [![dev dependency status][dep-dev-image]][dep-dev-url]
+
+<!-- [![browser support](https://ci.testling.com/ethereum/ethereum.js.png)](https://ci.testling.com/ethereum/ethereum.js) -->
+
+## Installation
+
+### Node.js
+
+    npm install ethereum.js
+
+### For browser
+Bower
+
+	bower install ethereum.js
+
+Component
+
+	component install ethereum/ethereum.js
+
+* Include `ethereum.min.js` in your html file.
+* Include [es6-promise](https://github.com/jakearchibald/es6-promise) or another ES6-Shim if your browser doesn't support ECMAScript 6.
+
+## Usage
+Require the library:
+
+	var web3 = require('web3');
+
+Set a provider (QtProvider, WebSocketProvider, HttpRpcProvider)
+
+	var web3.setProvider(new web3.providers.WebSocketProvider('ws://localhost:40404/eth'));
+
+There you go, now you can use it:
+
+```
+web3.eth.coinbase.then(function(result){
+  console.log(result);
+  return web3.eth.balanceAt(result);
+}).then(function(balance){
+  console.log(web3.toDecimal(balance));
+}).catch(function(err){
+  console.log(err);
+});
+```
+
+
+For another example see `example/index.html`.
+
+## Building
+
+* `gulp build`
+
+
+### Testing
 
 **Please note this repo is in it's early stage.**
