   2. And, send it to your friend (s/he should use be using the same operating system) (if you're using windows, then hers/his should be windows too)

   3. And then send your program to a friend with a different operating system.

      (So, you should compile your program for her operating system).

      For OSX, type: GOOS=darwin GOARCH=386 go build

      For Windows: GOOS=windows GOARCH=386 go build

      For Linux: GOOS=linux GOARCH=arm GOARM=7 go build

      You can find the full list in here: https://golang.org/doc/install/source#environment
