-# 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.webui.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.
