#Set these variables in .bash_profile (OS X) file
export GOPATH=$HOME/workspace
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/bin

setup.md

##Install Go for OS X (use homebrew).

• Install Homebrew

    ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    brew update

• Install GO

    brew install go

• Create a directory workspace in home folder

    mkdir workspace

• Setup GOPATH and GOROOT

    cd workspace
    export GOPATH=/Users/`whoami`/workspace

Install go in linux

• Download latest GO from Here

    wget https://storage.googleapis.com/golang/go1.6.3.linux-amd64.tar.gz
    tar -C /usr/local -xzf go1.6.3.linux-amd64.tar.gz

• Set GOPATH and PATH

    cd
    mkdir -p ~/workspace; echo "export GOPATH=$HOME/workspace" >> ~/.bashrc
    echo "export PATH=$PATH:$HOME/workspace/bin:/usr/local/go/bin" >> ~/.bashrc
    source ~/.bashrc

###Workspaces

• A workspace is a directory hierarchy with three directories at its root:
  • src contains Go source files,
  • pkg contains package objects, and
  • bin contains executable commands.

###Source repository
If your code in a source repository somewhere. then you should use the root of that source repository as your base path inside src. For instance, if you have a bitbucket account at bitbucket.org/user, that should be your base path.

    mkdir -p $GOPATH/src/bitbucket.org/user

###Your first program To Run a simple program, first choose a package path (bitbucket.org/user/hello)

 mkdir $GOPATH/src/bitbucket.org/user/hello

where hello is a package directory inside base path. and then create your first hello program (hello.go) inside package.

###Compile and Run

go install $GOPATH/src/bitbucket.org/user/hello
$GOPATH/bin/hello
