One of the greatest lessons I have learned in development is to always read the README.
Instead of asking a question on StackOverflow or some forum, I highly suggest reading the README first of the gem, module, and/or package. Not only will you learn more by doing it, but you will also grasp the important skill any employer looks for...self-motivation.
Any half-way decent software will have a solid README that should take care of most of the functionality and set-up.
With this being said, here is the README for this site.
