 The `PluginConfig` class is a NetBox-specific wrapper around Django's built-in [`AppConfig`](https://docs.djangoproject.com/en/stable/ref/applications/) class. It is used to declare NetBox plugin functionality within a Python package. Each plugin should provide its own subclass, defining its name, metadata, and default and required configuration parameters. An example is below:
 
 ```python

 A plugin can register its own submenu as part of NetBox's navigation menu. This is done by defining a variable named `menu` in `navigation.py`, pointing to an instance of the `PluginMenu` class. Each menu must define a label and grouped menu items (discussed below), and may optionally specify an icon. An example is shown below.

 Each menu item represents a link and (optionally) a set of buttons comprising one entry in NetBox's navigation menu. Menu items are defined as PluginMenuItem instances. An example is shown below.

 Declared subclasses should be gathered into a list or tuple for integration with NetBox. By default, NetBox looks for an iterable named `template_extensions` within a `template_content.py` file.
