+## Grimshot: a helper for screenshots within sway
+## Requirements:
+##  - `grim`: screenshot utility for wayland
+##  - `slurp`: to select an area
+##  - `swaymsg`: to read properties of current window
+##  - `wl-copy`: clipboard utility
+##  - `jq`: json utility to parse swaymsg output
+##  - `notify-send`: to show notifications
+## Those are needed to be installed, if unsure, run `grimshot check`
+##
+## See `man 1 grimshot` or `grimshot usage` for further details.
