# evennia/setup-database

# Use this action in a workflow for when you need to do initialization of database services
# (such as with PostgreSQL and MySQL) before you initiate unit tests that will employ that
# database service.

# NOTE: This action was intended for use with the core Evennia workflows ONLY.
