+## A simple tool to rename movies, written in Rust.
 
 This is made mostly due to [mnamer](https://github.com/jkwill87/mnamer) not having support for director's name, and partly because I wanted to try writing something useful in Rust.
 
 The expected syntax is:
 
-`movie_rename <filename(s)> [--dry-run] [--directory] [--help]`
-- There needs to be a config file names movie_rename.conf in your $XDG_CONFIG_HOME.
+`movie_rename <filename(s)> [-n|--dry-run] [-d|--directory] [-h|--help] [-v|--version]`
+- There needs to be a config file named 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`.

+.SH DESCRIPTION
+movie_rename is a simple tool to rename movies, written in Rust.
+.SH ARGUMENTS
+A list of filenames (or directory names, not both). -d or --directory must be passed to work with directories.
+.SH OPTIONS
+.TP
+-n, --dry-run
+Performs a dry run, without actually renaming anything.

+.TP
+-h, --help
+Print help information.
+.TP
+-v, --version
+Print version information.
+.SH CONFIG
+There needs to be a config file named movie_rename.conf in your $XDG_CONFIG_HOME.
+It should consist of two lines.
+.sp
+The first line should have your TMDb API key.
+.sp
+The second line should have a pattern, that will be used for the rename.
+.sp
+In the pattern, the variables need to be enclosed in {}, the supported variables are `title`, `year` and `director`.
