 You only need to specify `aerich.models` in one app, and must specify `--app` when running `aerich migrate` and so on.
 
+## Restore `aerich` workflow
+
+In some cases, such as broken changes from upgrade of `aerich`, you can't run `aerich migrate` or `aerich upgrade`, you
+can make the following steps:
+
+1. drop `aerich` table.
+2. delete `migrations/{app}` directory.
+3. rerun `aerich init-db`.
+
+Note that these actions is safe, also you can do that to reset your migrations if your migration files is too many.
+
+## Use `aerich` in application
+
+You can use `aerich` out of cli by use `Command` class.
+
+```python
+from aerich import Command
+
+command = Command(tortoise_config=config, app='models')
+await command.init()
+await command.migrate('test')
