 ### Multiple layout files
 
-Squib also supports the combination of multiple layout files. As shown in the above example, if you provide an `Array` of files then Squib will merge them sequentially. Colliding keys will be completely re-defined by the later file. Extends is processed after _each_ file. YAML merge keys are NOT supported across multiple files (use extends instead). Here's a demonstrative example:

+### Built-in Layout Files

+If your layout file is not found in the current directory, Squib will search for its own set of layout files (here's the latest the development version [on GitHub](https://github.com/andymeneely/squib/tree/master/lib/squib/layouts). See the `layouts.rb` sample found [here](https://github.com/andymeneely/squib/tree/master/samples/) for some demonstrative examples.

 ## Configuration File
 
 Squib supports various configuration properties that can be specified in an external file. The `config:` option in `Deck.new` can specify an optional configuration file in YML format. The properties there are intended to be immutable for the life of the Deck. The options include:
