Getting started: install Thor if you haven't.
gem install wycats-thor
You can install these tasks directly from the web:
thor install http://github.com/tongueroo/thor-tasks/tree/master/github.thor?raw=true
If you want to inspect and try out the tasks without installing, you should clone the repo:
git clone git://github.com/tongueroo/thor-tasks.git
cd thor-tasks
thor list
That command will get you a list of tasks together with their usage information. So, if you like them:
thor install github.thor --as Tongueroo
Later you'll wish to update:
git pull
thor update Tongueroo
On update, Thor will try to fetch the tasks from the same source you specified during install.
That's it. And now for a bit of fun.
