Now we setup a workspace by doing the following:

- Install Go as described in <http://golang.org/doc/install>
- Open an terminal and change the directory to your `$HOME` dir (My Documents for Windows).
- Create a new directory called `go` and add the following 3 folders to is: `src`, `pkg` and `bin`.
- Add an environment variable `GOPATH` with the value `$HOME/go`.
- Get the workshop code by executing: `go get github.com/pjvds/goworkshop`. The code will be located in `$GOPATH/src/github.com/pjvds/goworkshop`
- `cd` into that directory and open the `readme`.
