-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:

+```
+godep go build -v ./cmd/mist
+```
+
+Ethereum (CLI):

-================
-
-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.

-}
-```
-
-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!)
