 ------------
 
-A core goal of this app is to provide a clean experimentation interface.  To promote this end, we have provided a
-silo'ed code directory at ``src/widgets`` in which contributors should add their custom widget components.  In order to
-ensure our ability to maintain the code stability of the app, the code for these widgets should be strictly contained
-within the bounds of that directory.
-
-Once written, the widgets can be configured into one of our widget containers at ``src/containers/WidgetContainers``.
-This can include conditional logic, as well as Optimizely triggers. It is important to note that our integration tests
-will isolate and ignore these containers, and thus testing your widget is the response of the creator/maintainer of the
-widget itself.
-
-Some guidelines for writing widgets:
-
-* Code for the widget should be strictly confined to the ``src/widgets`` directory.
-* You can load data from the redux store, but should not add or modify fields in that structure.
-* Network events should be managed in component hooks, though can use our ``data/constants/requests:requestStates`` for
-  ease of tracking the request states.
