Vrobbler is a pretty simple Django-powered web app for scrobbling video plays from you favorite Jellyfin installation.
At the most basic level, you should be able to run pip install vrobbler to the latest version from pypi.org.
Then configure a handful of options in your vrobbler.conf files, which can live in /etc/ or /usr/local/etc/ depending on your configuration.
You can checkout the scrobbler.conf.example file in the source for this project, or refer to the following guide:
