Simple Issue Tracking is a software for tracking issue tickets, made enterily with Django Admin App.
It requires Django 1.9 and Python 3. For database, you can use the database engines supported by Django.
Rename(or copy) the file "Database_settings.py.sample" into "Database_settings", and configure it to use the database you want. (see https://docs.djangoproject.com/en/1.9/ref/settings/#databases )
After that, excecute "python3 manage.py migrate" to create the database, and "python3 manage.py createsuperuser" to create the Super User for the system.
There's no usergroups by default. You have to manually add the permissions for the "Ticket" model for the users in the Django admin, or define a group, give it the permissions, and then assign the group for the Users.
