title: Edit Ruby Gem locally and execute gem?
body: <p>For a project I'm working on, I have to do some work on an existing Ruby Gem. I haven't got much previous experience with Ruby and am struggling with a few aspects.</p>
  
  <p>I have the repository cloned locally. I need to edit the current files in the /lib/ directory, which I can do. Is it possible for me to compile the edited files into a Gem and run this Gem? Any help would be really appreciated.</p>
