-Ethereum Go developer client (c) Jeffrey Wilcke
+Ethereum Go Client © 2014 Jeffrey Wilcke.
 
-Ethereum is currently in its testing phase. The current state is "Proof
-of Concept 2". For build instructions see the [Wiki](https://github.com/ethereum/go-ethereum/wiki/Building-Edge).
+Current state: Proof of Concept 5.0 RC10.
 
-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.
+For the development package please see the [eth-go package](https://github.com/ethereum/eth-go).
 
 Build
 =======
 
-For build instruction please see the [Wiki](https://github.com/ethereum/go-ethereum/wiki/Building-Edge)
+To build Ethereal (GUI):
 
+`go get github.com/ethereum/go-ethereum/ethereal`
 
-Command line options
+To build the node (CLI):
+
+`go get github.com/ethereum/go-ethereum/ethereum`
+
+For further, detailed, build instruction please see the [Wiki](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go))
+
+General command line options
 ====================

 ============
 
-If you'd like to contribute to Ethereum Go please fork, fix, commit and
-send a pull request. Commits who do not comply with the coding standards
-are ignored. If you send pull requests make absolute sure that you
-commit on the `develop` branch and that you do not merge to master.
-Commits that are directly based on master are simply ignored.
