 Usage
 ```bash
-row clean [OPTIONS] <--directory|--submitted|--completed|--all>
+row clean [OPTIONS]

 [cache concepts page](../guide/concepts/cache.md) describes cases where you might need
 to clean the cache.
 
-## `[OPTIONS]`
-
-### `--all`
+By default, `row clean` removes all cache files. Pass one or more of the options to
+remove only selected caches.
 
-Remove all caches.
+## `[OPTIONS]`
