+# Django plugin
+
+This plugin adds completion for the [Django Project](https://www.djangoproject.com/) commands
+(`manage.py`, `django-admin`, ...).
+
+## Deprecation (2021-09-22)
+
+The plugin used to provide completion for `./manage.py` and `django-admin`, but Zsh already provides
+a better, more extensive completion for those, so this plugin is no longer needed.
+
+Right now a warning message is shown, but in the near future the plugin will stop working altogether.
+So you can remove it from your plugins and you'll automatically start using Zsh's django completion.
