-Ethereum Go is split up in several sub packages Please refer to each
-individual package for more information.
-  1. [eth](https://github.com/ethereum/eth-go)
-  2. [ethchain](https://github.com/ethereum/ethchain-go)
-  3. [ethwire](https://github.com/ethereum/ethwire-go)
-  4. [ethdb](https://github.com/ethereum/ethdb-go)
-  5. [ethutil](https://github.com/ethereum/ethutil-go)
-
-The [eth](https://github.com/ethereum/eth-go) is the top-level package
-of the Ethereum protocol. It functions as the Ethereum bootstrapping and
-peer communication layer. The [ethchain](https://github.com/ethereum/ethchain-go)
-contains the Ethereum blockchain, block manager, transaction and
-transaction handlers. The [ethwire](https://github.com/ethereum/ethwire-go) contains
-the Ethereum [wire protocol](http://wiki.ethereum.org/index.php/Wire_Protocol) which can be used
-to hook in to the Ethereum network. [ethutil](https://github.com/ethereum/ethutil-go) contains
-utility functions which are not Ethereum specific. The utility package
-contains the [patricia trie](http://wiki.ethereum.org/index.php/Patricia_Tree),
-[RLP Encoding](http://wiki.ethereum.org/index.php/RLP) and hex encoding
-helpers. The [ethdb](https://github.com/ethereum/ethdb-go) package
-contains the LevelDB interface and memory DB interface.
-
-This executable is the front-end (currently nothing but a dev console) for
-the Ethereum Go implementation.
-
-Deps
-====
-
-Ethereum Go makes use of a modified `secp256k1-go` and therefor GMP.
-
-Ubuntu 12+
-* `apt-get install gmp-dev`
- 
-OS X 10.9+: 
-* `brew install gmp`
+For the development package please see the [eth-go package](https://github.com/ethereum/eth-go).

 ============

-send a pull request. Commits who do not comply with the coding standards
-are ignored.
+If you would like to contribute to Ethereum Go, please fork, fix, commit and

+Commits that are directly based off of the `master` branch instead of the `develop` branch will be ignored.
