   module Components
 
     # Components::Base is the base class for ExpressTemplates view components.
     #
-    # View components are available as macros in ExpressTemplates and may be
-    # used to encapsulate common view patterns, behavior and functionality in
-    # reusable classes that can be shared within and across projects.
     #
-    # Components intended to provide a base framework for a library of reusable
-    # components to cut development time across a multitude of projects.
-    #
-    # Components gain their functionality through including Capabilities.
-    #
-    # Example capabilities include:
-    #
-    # * Managing related ExpressTemplate fragments
-    # * Compiling template fragments for evaluation in a View Context
-    # * Specifying rendering logic to be executed in the View Context
-    # * Potentially referencing external assets that may be required
-    #   for the component to work.
-    #
-    # Components::Base includes the following capabilities:
-    #
-    # * Capabilities::Templating
-    # * Capabilities::Rendering
-    # * Capabilities::Wrapping
-    # * Capabilities::Iterating
