This should be, god willing and the creek don't rise, a testing setup fully configured with Rspec, Cucumber, Spork, and Guard in Thoughtbot's recommended manner.
Ideally, you can just clone this, change the app name in the config files (search for “thoughtful_testing” and “ThoughtfulTesting”) to the name of your app, and be good to go.
You'll also want to rm-rf .git and .gitignore.
If you're planning on committing your own project to GitHub, you should be able to just do the following (once you've created your repo on GitHub):
git add README
git commit -m 'first commit'
git remote add origin href=“https://github.com/[username]/[project_name].git”>github.com/[username]/
git push origin master
That said, I haven't actually tested this yet. So if there's a problem, let me know.
