+# smart-enter.yazi
+
+[`Open`][open] files or [`enter`][enter] directories all in one key!
+
+## Installation
+
+```sh
+ya pack -a yazi-rs/plugins:smart-enter
+```
+
+## Usage
+
+Bind your <kbd>l</kbd> key to the plugin, in your `~/.config/yazi/keymap.toml`:
+
+```toml
+[[manager.prepend_keymap]]
+on   = "l"
+run  = "plugin --sync smart-enter"
+desc = "Enter the child directory, or open the file"
+```
+
+## Advanced
+
+By default, `hovered = true` is passed to the [`open`][open] command, make the behavior consistent with [`enter`][enter] avoiding accidental triggers,
+which means both will only target the currently hovered file.
+
+If you still want `open` to target multiple selected files, add this to your `~/.config/yazi/init.lua`:
+
+```lua
+require("smart-enter"):setup {
+	open_multi = true,
+}
+```
+
+## License
+
+This plugin is MIT-licensed. For more information check the [LICENSE](LICENSE) file.
