+
+### Background
+
+Channels are fundamental elements of Stream Chat and constitute shared spaces which allow users to
+message each other. 1:1 conversations and groups are both examples of channels, albeit with some (distinct/non-distinct)
+differences. Displaying the list of channels that a user is a part of is a pattern that is part of
+most messaging apps.
+
+The `ChannelListView` widget allows displaying a list of channels to a user. By default, this is NOT
+ONLY the channels that the user is a part of. This section goes into setting up and using a `ChannelListView`
+widget.
+
+### Basic Example
+
+Here is a basic example of the `ChannelListView` widget. It consists of the main widget itself, a `Filter`
+to filter only the channels that the user is a part of, sorting by last message time, pagination params,
+and the widget to use when a particular channel is clicked.
 
 ```dart
 class ChannelListPage extends StatelessWidget {

+This example by default displays the channels that a user is a part of. Now let's look at customizing
+the widget.
 
-Make sure to have a [StreamChat] ancestor in order to provide the

-information about the channels.

-The widget uses a [ListView.custom] to render the list of channels.
+A common aspect of the widget needed to be tweaked according to each app is the Channel Preview (the
+Channel tile in the list). To do this, we use the `channelPreviewBuilder` param like this:
+
+```dart
+ChannelListView(
+  ...
+  channelPreviewBuilder: (context, channel) {
+    return ListTile(
+      tileColor: Colors.amberAccent,
+      title: Center(
+        child: ChannelName(),
+      ),
+    );
+  },
+),
+```
+
+Which gives you a new Channel preview in the list:
