+# what-size.yazi
+
+A plugin for [yazi](https://github.com/sxyazi/yazi) to calculate the size of the current selection or the current working directory (if no selection is made).
+
+## Compatibility
+
+- yazi `0.4.x` since commit `2780de5aeef1ed16d1973dd6e0cd4d630c900d56` ([link](https://github.com/pirafrank/what-size.yazi/commit/2780de5aeef1ed16d1973dd6e0cd4d630c900d56)).
+- yazi `0.3.x` up to commit `f08f7f2d5c94958ac4cb66c51a7c24b4319c6c93` ([link](https://github.com/pirafrank/what-size.yazi/commit/f08f7f2d5c94958ac4cb66c51a7c24b4319c6c93)).
+
+## Requirements
+
+- `du` on Linux. macOS and Windows support is planned.
+
+## Installation
+
+```sh
+ya pack -a 'pirafrank/what-size'
+```
+
+## Usage
+
+Add this to your `~/.config/yazi/keymap.toml`:
+
+```toml
+[manager]
+prepend_keymap = [
+  { on   = [ ".", "s" ], run  = "plugin what-size", desc = "Calc size of selection or cwd" },
+]
+```
+
+If you want to copy the result to clipboard, you can add `--clipboard` or `-c` as first argument:
+
+```toml
+[manager]
+prepend_keymap = [
+  { on   = [ ".", "s" ], run  = "plugin what-size --args='--clipboard'", desc = "Calc size of selection or cwd" },
+]
+```
+
+Change to whatever keybinding you like.
