+    ```
+- Apply all pending migrations
+    ```sh
+    cargo run
+    ```
+    ```sh
+    cargo run -- up
+    ```
+- Apply first 10 pending migrations

+    cargo run -- up -n 10
+    ```
+- Rollback last applied migrations
+    ```sh
+    cargo run -- down
+    ```
+- Rollback last 10 applied migrations
+    ```sh
+    cargo run -- down -n 10
+    ```
+- Drop all tables from the database, then reapply all migrations
+    ```sh
+    cargo run -- fresh
+    ```
+- Rollback all applied migrations, then reapply all migrations
+    ```sh
+    cargo run -- refresh
