Install go with brew, and running the gotour

Question

I was following the http://tour.golang.org/ untill I got to the third step about that tells you that you can install the gotour on your system. After that I've installed the go language with brew by:

brew install hg
brew install go

Then I downloaded the gotour by:

go get code.google.com/p/go-tour/gotour

When I tried to launch the gotour it didnt recognise the command:

$ gotour
-bash: gotour: command not found

and

$ go gotour

and

$ ./gotour

So I tried to see the go path and it was empty,

echo $GOPATH

so I defined the GOPATH:

GOPATH=/usr/local/Cellar/go/1.0.2/src/pkg/code.google.com/p/
export GOPATH

Now I can run the gotour by runing

./gotour

But I'm insecure about my go enviroment.. wasn't I suposed to be able to run gotour by

go run gotour

or just by typing (like is described on this website http://www.moncefbelyamani.com/how-to-install-the-go-tour-on-your-mac/):

gotour

I would like to know if i'm doing things the right way since I'm new to the go programing language.

Installing go 1.4 with homebrew on OSX:

1) Create Directories

mkdir $HOME/Go
mkdir -p $HOME/Go/src/github.com/user

2) Setup your paths

export GOPATH=$HOME/Go
export GOROOT=/usr/local/opt/go/libexec
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/bin

3) Install Go

brew install go

4) "go get" the basics

go get golang.org/x/tools/cmd/godoc

5) Start here: https://golang.org/doc/code.html at "your first program"
