-# 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.
-
-For an example see `index.html`.
-
-**Please note this repo is in it's early stage.**

+# 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
+```

+= Integration tests for eth protocol and blockpool 
+
+This is a simple suite of tests to fire up a local test node with peers to test blockchain synchronisation and download. 
+The scripts call ethereum (assumed to be compiled in go-ethereum root). 
+
+To run a test:
+
+    . run.sh 00 02
+
+Without arguments, all tests are run. 
+
+Peers are launched with preloaded imported chains. In order to prevent them from synchronizing with each other they are set with `-dial=false` and `-maxpeer 1` options. They log into `/tmp/eth.test/nodes/XX` where XX is the last two digits of their port. 
+
+Chains to import can be bootstrapped by letting nodes mine for some time. This is done with 
+
+    . bootstrap.sh 
+
+Only the relative timing and forks matter so they should work if the bootstrap script is rerun. 
+The reference blockchain of tests are soft links to these import chains and check at the end of a test run. 
+
+Connecting to peers and exporting blockchain is scripted with JS files executed by the JSRE, see `tests/XX.sh`. 
+
+Each test is set with a timeout. This may vary on different computers so adjust sensibly. 
+If you kill a test before it completes, do not forget to kill all the background processes, since they will impact the result. Use:
+
+    killall ethereum
+
