      ### Further setup [optional]
      
      The `rvm` install script adds `rvm` loading lines into 
      `~/.profile` and `~/.bash_profile` by default. 
      
          export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
          
          [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
      
      Depending on your current init files settings,
      you may want to have a look at that.
