-    Register a subview for a core model.
+    This decorator can be used to "attach" a view to any model in NetBox. This is typically used to inject
+    additional tabs within a model's detail view. For example, to add a custom tab to NetBox's dcim.Site model:

-        model: The Django model class with which this view will be associated
-        name: The name to register when creating a URL path
-        view: A class-based or function view, or the dotted path to it (e.g. 'myplugin.views.FooView')

+        model: The Django model class with which this view will be associated.
+        name: The string used to form the view's name for URL resolution (e.g. via `reverse()`). This will be appended
+            to the name of the base view for the model using an underscore.
+        path: The URL path by which the view can be reached (optional). If not provided, `name` will be used.
