3. Create a patch with Python configurations (More info below)
4. Run tutor config save
5. Run tutor dev/local start codejailservice

How to create a patch

You can clone this plugin and add a file with the patch name, and inside the file, add the Python configuration. The file needs to be inside the patches folder: https://github.com/eduNEXT/tutor-contrib-codejail/tree/main/tutorcodejail/patches. You should have something like tutorcodejail/patches/codejail-common-settings, and inside:

NAME_OF_YOUR_VARIABLE = <value>    # Example: True

Or you can add the patch in another plugin following this documentation: https://docs.tutor.edly.io/tutorials/plugin.html#modifying-existing-files-with-patches
