# Including apps in your project

Since Apps are supposed to be "pluggable", in that they are not specific to a single project, you need to tell your project which apps are to be used in it explicitly. To do this you have to update `INSTALLED_APPS` in the `settings.py` file of your project to include the path to the app's configuration class. In the case of the tutorial, this configuration is under `polls.apps.PollsConfig`
