+# chmod.yazi
+
+Execute `chmod` on the selected files to change their mode. This plugin is only available on Unix platforms since it relies on [`chmod(2)`](https://man7.org/linux/man-pages/man2/chmod.2.html).
+
+## Installation
+
+```sh
+ya pack -a yazi-rs/plugins#chmod
+```
+
+## Usage
+
+Add this to your `~/.config/yazi/keymap.toml`:
+
+```toml
+[[manager.prepend_keymap]]
+on   = [ "c", "m" ]
+run  = "plugin chmod"
+desc = "Chmod on selected files"
+```
+
+Make sure the <kbd>c</kbd> => <kbd>m</kbd> key is not used elsewhere.
