Starting your own application
To start hacking on your own RingoJS application, use the ringo-admin create script to create a new app:
$ ringo-admin create [app directory]
If you don't pass the app directory on the command line the script will prompt you for it. Once the application has been created you can start it by running its main.js script:
$ ringo [app directory]/main.js
Packages for Ringo
To install additional Ringo packages you can either use the bare bones
ringo-admin install command or the more advanced rp Ringo package manager.
