go version go1.8.3 darwin/amd64

Test that Go was installed: https://golang.org/doc/install?download=go1.8.3.darwin-amd64.pkg#testing

$ mkdir go
$ echo $GOPATH
/Users/vjeffrey/go
$ echo $GOBIN
/Users/vjeffrey/go/bin
$ cd go
$ mkdir -p src/hello
$ cd src/hello
$ vi hello.go

package main

import "fmt"
