# `contrib` packages

Django aims to follow Python’s “batteries included” philosophy. It ships with a variety of extra, optional tools that solve common Web-development problems.

This code lives in `django/contrib` in the Django distribution. This document gives a rundown of the packages in `contrib`, along with any dependencies those packages have.

Note

For most of these add-ons – specifically, the add-ons that include either models or template tags – you’ll need to add the package name (e.g., `'django.contrib.redirects'`) to your `INSTALLED_APPS` setting and re-run `manage.py migrate`.
