 Note
 :::
 If your Tortoise-ORM app is not default `models`, you must specify
 `--app` like `aerich --app other_models init-db`.

 ### Update models and make migrate
 ```shell
-$ aerich migrate --name drop_column
+> aerich migrate --name drop_column

 ```
 Format of migrate filename is
-`{version_num}_{datetime}_{name|update}.json`
+`{version_num}_{datetime}_{name|update}.json`.
 And if `aerich` guess you are renaming a column, it will ask `Rename {old_column} to {new_column} [True]`, you can choice `True` to rename column without column drop, or choice `False` to drop column then create.
 If you use `MySQL`, only MySQL8.0+ support `rename..to` syntax.
 ### Upgrade to latest version

 ## Limitations
 - Not support `rename column` now.
 - `Sqlite` and `Postgres` may not work as expected because I don\'t
  use those in my work.
 ## Support this project
 - Just give a star!
 - Donation.
