 # BirdXplorer Migrations
+
+## Alembic によるマイグレーション
+
+### 前提条件
+
+- `birdxplorer_common` のインストールが完了していること
+- `birdxplorer_migration` のインストールが完了していること
+- `.env` ファイルに `BX_STORAGE_SETTINGS__PASSWORD` が設定されていること
+  - DB のデフォルトホスト名 `db` が解決できない場合は `BX_STORAGE_SETTINGS__HOST` も設定すること
+
+### 現在のマイグレーションを適用する
+
+データベースのスキーマを最新の状態にします。
+
+`alembic.ini` があるディレクトリの場合:
+
+```bash
+alembic upgrade head
+```
+
+`alembic.ini` が別の場所にある場合:
+
+```bash
+alembic upgrade head -c /path/to/alembic.ini
+```
+
+### 新しいマイグレーションを作成する
+
+データベースのスキーマを変更した場合、以下の手順で新しいマイグレーションを作成します。
+
+`alembic.ini` があるディレクトリの場合:
+
+```bash
+alembic revision --autogenerate -m "マイグレーションの説明"
+```
+
+`alembic.ini` が別の場所にある場合:
+
+```bash
+alembic revision --autogenerate -m "マイグレーションの説明" -c /path/to/alembic.ini
+```
