  This gem contains only the Ruby libraries for the RVM Ruby API.

  In order to install RVM please use one of the methods listed in the
  documentation:

    https://rvm.beginrescueend.com/rvm/install/

  such as,

    bash < <(curl -s -B https://rvm.beginrescueend.com/install/rvm)

  followed by placing the sourcing line in your ~/.bash_profile or wherever may
  be appropriate for your setup (example, .zshenv, /etc/profile, ...):

    # Load RVM into a shell session *as a function*
    [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

  After completing setup please open a new shell to use RVM and be sure to run
  'rvm notes' to gain a list of dependencies to install before installing the
  first Ruby. You can read more details about this process on the above
  mentioned install page as well as the basics page:

    https://rvm.beginrescueend.com/rvm/basics/

  Enjoy!
