I am new to Ruby and am trying to download the Framework Dashing (<http://dashing.io/>)

Here is what I have done so far:

* Downloaded RubyDownloader and ran it
* Downloaded dashing-1.3.4.gem
* Opened Start Command Prompt with Ruby

I am now currently confused on what to do next. I have tried reading and watching many tutorials and all it suggests is to install more software.

Any help pointing me in the right direction would be great!
