+The core loads all models imported in `__init__.py`.
+
+# Migrations
+
+You might use the alembic command lines to setup migration here.
+
+Run the command in the specific `models` folder
+
+## Create a new revision in `versions`:
+
+`alembic revision -m "name" --autogenerate --rev-id REV_ID`
+
+Please use the actual naming convention. E.g. `-m "name" --autogenerate  --rev-id 000001`.
+
+## Upgrade to a new revision:
+
+`alembic upgrade REV_ID`
+
+## Stamp to an actual version (may be needed before upgrade or create a new revision):
+
+`alembic stamp --purge REV_ID`
