+; # Supervisor Config File (for docker build)
+;
+; This config file is specific to the InvenTree docker build!
+;
+; There are two separate processes which must be managed:
+;
+; ## Web Server
+; The InvenTree server must be launched and managed as a process
+; The recommended way to handle the web server is to use gunicorn
+;
+; ## Background Tasks
+; A background task manager processes long-running and periodic tasks
+; InvenTree uses django-q for this purpose
