Run berks install
Berks looks at the source of cookbooks (i.e. Supermarket) and makes available to you all of the cookbooks that you tell it in your metadata.rb file with the depends resource.
When you converge your depends resources, it creates a Berksfile.lock file which lists all of the dependencies from the other cookbooks from which your available cookbooks draw.
To run those cookbooks, go to the default.rb file in recipes and add the recipes from those dependent cookbooks that you need to run using the include_recipe resource.
