 The expected syntax is:
 
-`movie_rename <filename(s)> [--dry-run] [--help]`
+`movie_rename <filename(s)> [--dry-run] [--directory] [--help]`
 - There needs to be a config file names movie_rename.conf in your $XDG_CONFIG_HOME.
 - It should consist of two lines. The first line should have your TMDb API key.
 - The second line should have a pattern, that will be used for the rename.
 - In the pattern, the variables need to be enclosed in {{}}, the supported variables are `title`, `year` and `director`.
 - Default pattern is `{title} ({year}) - {director}`. Extension is always kept.
+- Passing `--directory` assumes that the arguments are directory names, which contain exactly one movie and optionally subtitles.
 
 I plan to add more variables in the future. Support for TV Shows will not be added, since [tvnamer](https://github.com/dbr/tvnamer) does that excellently.
