-# ethereumjs.github.io
+This is a collection of libraries and utilities for [Ethereum](https://ethereum.org).
+
+## Use cases
+
+### Creating an online wallet?
+
+Check out [keythereum](https://github.com/ethereumjs/keythereum) for managing keys and [ethereumjs-tx](https://github.com/ethereumjs/ethereumjs-tx) for creating transactions with them.
+
+### Creating a Dapp?
+
+You will need to interface with the Ethereum network. [web3.js](https://github.com/ethereumjs/web3.js) provides a complete RPC interface from Javascript. If looking for a more lightweight option, [ethereumjs-abi](https://github.com/axic/ethereumjs-abi) or [solidity.js](https://github.com/ethereumjs/solidity.js) can handle the ABI encoding.
+
+### Interested in running a node?
+
+See [node-blockchain-server](https://github.com/ethereumjs/node-blockchain-server). It is in a pretty rough state at the moment, but at least can download the blockchain.
+
+## Full list of repos
