+A Widget For Building A List Of Channels
+
+### Background
+
+The UI SDK of Stream Chat supplies a `ChannelListView` class that builds a list of channels fetching
+according to the filters and sort order given. However, in some cases, implementing novel UI is necessary
+that cannot be done using the customization approaches given in the widget.
+
+To do this, we extracted the logic required for fetching channels into a 'Core' widget - a widget that
+fetches channels in the expected way via the usual params but does not supply any UI and instead
+exposes builders to build the UI in situations such as loading, empty data, errors, and on data received.
+
+### Basic Example
+
 `ChannelListCore` is a simplified class that allows fetching a list of
 channels while exposing UI builders.

+A Widget Dedicated To The Management Of A Channel List With Pagination.
+
+### Background
+
+Most widgets in the Core SDK are focused on fetching a particular type of object from Stream Chat - channels,
+messages, users, etc. The BLoC widgets bundle up the base functions used to fetch data as well as the current
+data fetched by the respective functions. Furthermore, the Core widgets use this BLoC to fetch new or
+existing data and build UI based on it.
+
+All Core and UI widgets which focus on fetching a list of objects need to have their respective functions
+above them in the widget tree. The ChannelListCore and ChannelListView require the ChannelsBloc
+above them in the widget hierarchy without which they will fail.
+
+### Understanding The Widget
+
 `ChannelsBloc` is used together with `ChannelListCore` to manage a list of
 Channels with pagination, re-ordering, querying and other operations
 associated with Channels.
