Site-specific app for Rails docs
Unless you’re a Rails genius, you probably need to frequently reference the Rails API docs. And if you haven’t discovered it yet, railsapi.com is awesome.
Better yet, head over to railslogo.com and grab the Creative Commons licensed logo to use as the icon.
Now my only complaint is that I don’t have docs for Ruby and other gems in this app, but I have a hunch that it won’t be long until that changes.
