 For an early peek, have a looki at this [video](https://youtu.be/D5ok7jh7AOg)
 
 # Todo
 
 The Ethereum protocol is currenty heavily in development, thus so is this implementation.
-You can find a todo-list right [here](TODO.md) and the [milestone schedule](https://github.com/ethereum/ethereumj/milestones).

 # Documentation
 
 To start you can visit [Ethereum.org](https://www.ethereum.org) and if you are looking for more information on the concept, the [ethereum white paper](https://github.com/ethereum/wiki/wiki/%5BEnglish%5D-White-Paper) is a good place to start as it outlines the vision. For the more technical minded, a protocol description can be found in the [yellow paper](http://gavwood.com/Paper.pdf) by Gavin Wood.
