To get started, perform the following steps:

1. Install django-mptt in your virtual environment using the following command:

(env)$ pip install django-mptt==0.10.0

2. Create the categories and ideas apps if you have not done so already. Add those apps as well as mptt to INSTALLED_APPS in the settings, as follows:

# myproject/settings/_base.py
INSTALLED_APPS = [
    # …
    "mptt",
    # …
    "myproject.apps.categories",
    "myproject.apps.ideas",
]
