-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), switch to the go-ethereum repository root folder, and build/install the executable you need:
-
-Mist (GUI):
-
-```
-godep go build -v ./cmd/mist
-```
-
-Geth (CLI):
-
-```
-godep go build -v ./cmd/geth
-```
-
-Instead of `build`, you can use `install` which will also install the resulting binary.
