# Extensions

Extensions provide helper or class methods for Sinatra and Padrino applications.
See [the Sinatra extensions page](http://www.sinatrarb.com/extensions-wild.html)
for more information about this topic.

We also have some 3rd party extensions (ex: for
ActiveRecord/Sequel/Mongoid, etc ...) that are useful for web developers.

## Usage

If the extension is a gem put it in Gemfile, otherwise create a file under your
lib directory.
