Docs don't explain full installation steps or other necessary prerequisites to using django-parsley

Having a basic issue after installing django-parsley - the following error is displaying when I try to run the python manage.py runserver command:

from parsley.decorators import parsleyfy
ModuleNotFoundError: No module named 'parsley'

If parsley is a different dependency that must be installed in the project, could the docs be updated to reflect that? I can't figure out what to do to get this working.
