-# Backend – automatické migrace (Alembic)
-
-## Automatické migrace
-
-Při spuštění backendu v Dockeru se automaticky provedou migrace databáze pomocí Alembic (`alembic upgrade head`).
-
-## Ruční práce s migracemi
-
-- Vytvoření nové migrace podle modelů:
-  ```sh
-  export DATABASE_URL='mysql+asyncmy://root:strongpassword@localhost:3306/group_project'
-  alembic revision --autogenerate -m "popis migrace"
-  ```
-- Aplikace migrací:
-  ```sh
-  export DATABASE_URL='mysql+asyncmy://root:strongpassword@localhost:3306/group_project'
-  alembic upgrade head
-  ```
-
-## Poznámky
-- Pro autogeneraci migrací je nutné mít nainstalován balíček `pymysql`.
-- Modely pro migrace jsou v `app/db.py`.
-- Konfigurace Alembic je v `alembic.ini` a `alembic/env.py`.
