RuntimeError: Model class simple_certmanager.models.Certificate doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

Adding zgw-consumers as a dependency without adding simple_certmanager to INSTALLED_APPS causes error when running migrations.

I think it can be added to the README?

Yep, and to docs/quickstart.rst too!
