-For further, detailed, build instruction please see the [Wiki](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go))
+As of POC-8, go-ethereum uses [Godep](https://github.com/tools/godep) to manage dependencies. Assuming you have [your environment all set up](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go)), switch to the go-ethereum repository root folder, and build/install the executable you need:
+
+Mist (GUI):
+
+```
+godep go build -v ./cmd/mist
+```
+
+Ethereum (CLI):
+
+```
+godep go build -v ./cmd/ethereum
+```
+
+Instead of `build`, you can use `install` which will also install the resulting binary.
+
+For prerequisites and detailed build instructions please see the [Wiki](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go))
+
+If you intend to develop on go-ethereum, check the [Developers' Guide](https://github.com/ethereum/go-ethereum/wiki/Developers'-Guide)

+* `ethtest` test tool which runs with the [tests](https://github.com/ethereum/testes) suite: 
   `cat file | ethtest`.
 * `evm` is a generic Ethereum Virtual Machine: `evm -code 60ff60ff -gas
   10000 -price 0 -dump`. See `-h` for a detailed description.
-* `rlpdump` converts a rlp stream to `interface{}`.

-General command line options
+Command line options
 ============================
 
+Both `mist` and `ethereum` can be configured via command line options, environment variables and config files.
+
+To get the options available:
+
 ```
-== Shared between ethereum and Mist ==
-
-= Settings
--id      Set the custom identifier of the client (shows up on other clients)
--port    Port on which the server will accept incomming connections
--upnp    Enable UPnP
--maxpeer Desired amount of peers
--rpc     Start JSON RPC
--dir     Data directory used to store configs and databases
-
-= Utility 
--h         This
--import    Import a private key
--genaddr   Generates a new address and private key (destructive action)
--dump      Dump a specific state of a block to stdout given the -number or -hash
--difftool  Supress all output and prints VM output to stdout
--diff      vm=only vm output, all=all output including state storage
-
-Ethereum only
-ethereum [options] [filename]
--js        Start the JavaScript REPL
-filename   Load the given file and interpret as JavaScript
--m       Start mining blocks
-
-== Mist only ==
-
--asset_path    absolute path to GUI assets directory
+ethereum -help
 ```

+If you'd like to contribute to go-ethereum please fork, fix, commit and
 send a pull request. Commits who do not comply with the coding standards
 are ignored (use gofmt!). 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.
 
-For dependency management, we use [godep](https://github.com/tools/godep). After installing with `go get github.com/tools/godep`, run `godep restore` to ensure that changes to other repositories do not break the build. To update a dependency version (for example, to include a new upstream fix), run `go get -u <foo/bar>` then `godep update <foo/...>`. To track a new dependency, add it to the project as normal than run `godep save ./...`. Changes to the Godeps folder should be manually verified then commited.

-
-Coding standards
-================
-
-Sources should be formatted according to the [Go Formatting
-Style](http://golang.org/doc/effective_go.html#formatting).
-
-Unless structs fields are supposed to be directly accesible, provide
-Getters and hide the fields through Go's exporting facility.
-
-When you comment put meaningful comments. Describe in detail what you
-want to achieve.
-
-*wrong*
-
-```go
-// Check if the value at x is greater than y
-if x > y {
-    // It's greater!
-}
-```
-
-Everyone reading the source probably know what you wanted to achieve
-with above code. Those are **not** meaningful comments.

-While the project isn't 100% tested I want you to write tests non the
-less. I haven't got time to evaluate everyone's code in detail so I
-expect you to write tests for me so I don't have to test your code
-manually. (If you want to contribute by just writing tests that's fine
-too!)
