-# 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. 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 [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.**
-
-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
-```
