Congrats!

Make sure that all works well by running the application generator command:
    $ rails new railsgirls

If you encounter the message:
    The program 'rails' is currently not installed.

It is just a hiccup with the shell, solutions:
    $ source ~/.rvm/scripts/rvm
    Allow login shell, example http://rvm.io/integration/gnome-terminal/"
