+If you run an [Arch Linux based distribution without systemd](https://wiki.parabola.nu/OpenRC), you will need to add the `setuid-bit` and the `cap_sys_tty_config` ([issue 1022](https://github.com/SirCmpwn/sway/issues/1022)) to your `/usr/bin/sway` file, or otherwise it will not start.
+
+### manually
+
+These are the commands, that you need to run as *root* after each sway installation/update:
+
+```
+setcap cap_sys_tty_config=ep /usr/bin/sway
+chmod +s /usr/bin/sway
+```
+
+### automated
+
+Place the following two [hook](https://www.archlinux.org/pacman/alpm-hooks.5.html) files in `/etc/pacman.d/hooks` (create the folder, if it does not exist).
+
+`sway-setuid.hook`
+```
