+[Embed.ly](http://embed.ly/) supports more than 400 content providers. Be sure to check the [embed.ly providers list](http://embed.ly/providers) prior to implementing your own custom provider. If your desired provider is already supported, simply add its URL to the bottom of the existing list `/lib/providers/embedly_patterns.def`.

 ### Implementing your own providers
 
 You are able to easily implement additional providers by creating an object which implements the `#handles_url?(url)` and `#get_data(url, other_params)` methods. Take a look at the existing provider classes for examples.
