+# Ethereum JavaScript API
+
+This is the Ethereum compatible [JavaScript API](https://github.com/ethereum/wiki/wiki/JavaScript-API)
+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
+
+[![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 [bignumber.js](https://github.com/MikeMcl/bignumber.js/)
+
+## 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:
+
+```
+var coinbase = web3.eth.coinbase;
+var balance = web3.eth.balanceAt(coinbase);
+```
+
+
+For another example see `example/index.html`.
+
+## Contribute!
+
+### Requirements
+
+* Node.js
+* npm
+* gulp (build)
+* mocha (tests)
+
+```bash
+sudo apt-get update
+sudo apt-get install nodejs
+sudo apt-get install npm
+sudo apt-get install nodejs-legacy
+```
+
+### Building (gulp)
+
+```bash
+npm run-script build
+```
+
+
+### Testing (mocha)
+
+```bash
+npm test
+```
+
+**Please note this repo is in it's early stage.**
+
+If you'd like to run a WebSocket ethereum node check out
+[go-ethereum](https://github.com/ethereum/go-ethereum).
+
+To install ethereum and spawn a node:
+
+```
+go get github.com/ethereum/go-ethereum/ethereum
+ethereum -ws -loglevel=4
+```
