+# Database Migrations
+
+This directory contains all the database migrations for the web app.
+Migrations are done using the [`peewee-migrate`](https://github.com/klen/peewee_migrate) library.
+
+Migrations are automatically ran at app startup.
+
+## Creating a migration
+
+Have you made a change to the schema of an existing model?
+You will need to create a migration file to ensure that existing databases are updated for backwards compatibility.
+
+1. Have a database file (`webui.db`) that has the old schema prior to any of your changes.
+2. Make your changes to the models.
+3. From the `backend` directory, run the following command:
+   ```bash
+   pw_migrate create --auto --auto-source apps.web.models --database sqlite:///${SQLITE_DB} --directory apps/web/internal/migrations ${MIGRATION_NAME}
+   ```
+   - `$SQLITE_DB` should be the path to the database file.
+   - `$MIGRATION_NAME` should be a descriptive name for the migration.
+4. The migration file will be created in the `apps/web/internal/migrations` directory.
