+## Overview
 
 To create a custom plugin, subclass from `BasePlugin` (client or broker) or `BaseAuthPlugin` (broker only)
 or `BaseTopicPlugin` (broker only).  Each custom plugin may define settings specific to itself by creating
-a nested (or inner) `dataclass` named `Config` which declares each option and a default value (if applicable). A
-plugin's configuration dataclass will be type-checked and made available from within the `self.context` instance variable.

+??? note "Example: custom plugin within broker script"
+    The example `samples/broker_custom_plugin.py` demonstrates how to load a custom plugin
+    by passing a config dictionary when instantiating a `Broker`. While this example is functional,
