 """
-This module is an example of a barebones QWidget plugin for napari
+This module contains four napari widgets declared in
+different ways:
 
-It implements the Widget specification.
-see: https://napari.org/stable/plugins/guides.html?#widgets
+- a pure Python function flagged with `autogenerate: true`
+    in the plugin manifest. Type annotations are used by
+    magicgui to generate widgets for each parameter. Best
+    suited for simple processing tasks - usually taking
+    in and/or returning a layer.
+- a `magic_factory` decorated function. The `magic_factory`
+    decorator allows us to customize aspects of the resulting
+    GUI, including the widgets associated with each parameter.
+    Best used when you have a very simple processing task,
+    but want some control over the autogenerated widgets. If you
+    find yourself needing to define lots of nested functions to achieve
+    your functionality, maybe look at the `Container` widget!
+- a `magicgui.widgets.Container` subclass. This provides lots
+    of flexibility and customization options while still supporting
+    `magicgui` widgets and convenience methods for creating widgets
+    from type annotations. If you want to customize your widgets and
+    connect callbacks, this is the best widget option for you.
+- a `QWidget` subclass. This provides maximal flexibility but requires
+    full specification of widget layouts, callbacks, events, etc.
+
+References:
+- Widget specification: https://napari.org/stable/plugins/guides.html?#widgets
+- magicgui docs: https://pyapp-kit.github.io/magicgui/
