+
+* `mist` Official Ethereum Browser
+* `ethereum` Ethereum CLI
+* `ethtest` test tool which runs with the [tests](https://github.com/ethereum/testes) suit: 
+  `ethtest "`cat myfile.json`"`.
+* `evm` is a generic Ethereum Virtual Machine: `evm -code 60ff60ff -gas
+  10000 -price 0 -dump`. See `-h` for a detailed description.

+# 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.**
+
+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
