# Getting started

## Installation

### Go

First, create a `$HOME/mygo` directory and its src subdirectory:

    mkdir -p $HOME/mygo/src # create a place to put source code

Next, set it as the GOPATH. You should also add the bin subdirectory to your PATH environment variable so that you can run the commands therein without specifying their full path. To do this, add the following lines to `$HOME/.profile` (or equivalent):

    export GOPATH=$HOME/mygo
    export PATH=$PATH:$HOME/mygo/bin

Now you can install Go:

    brew install go


### Dependencies

Install leveldb and protobuf dependencies:

    brew install leveldb protobuf


### Libraries

    go get code.google.com/p/goprotobuf/{proto,protoc-gen-go}
