2. Install Go using the installer

• Web Based Compiler (no need to install anything)

How Do I Start Writing Code

You need to setup your GOPATH, which is where all of your code will reside

• Mac:

export GOPATH=/Users/mack/go

Let's Write a Simple Program

Open up your favorite editor and create a new file, put the content list below in the file and save it in /Users/mack/go/src/example/main.go

package main

import "fmt"

func main() {
    fmt.Println("Hello Detroit Black Tech")
}

Execute Your First Go Program

cd /Users/mack/go/src/example
go run main.go
