+First, you'll need go. If you don't have it: [Download Go 1.4+](https://golang.org/dl/).

+You'll need to add Go's bin directories to your `$PATH` environment variable e.g., by adding these lines to your `/etc/profile` (for a system-wide installation) or `$HOME/.profile`:
 ```
 export PATH=$PATH:/usr/local/go/bin
 export PATH=$PATH:$GOPATH/bin

 To start using ipfs, you must first initialize ipfs's config files on your

 the optional arguments it takes. After initialization is complete, you can use
