Wagtail Download Counter is an add-on for Wagtail CMS that keeps track of the number of times a document has been downloaded and shows the count in the Wagtail admin interface.

In your settings file add the following:

INSTALLED_APPS = [
    ...
    'downloadcounter',
    ...
]

Make sure you add downloadcounter before wagtail.wagtaildocs in the installed apps.

Run migrations and you're set.
