 - It sends an interrupt (Ctrl-C) and one of 5 encouraging messages!
 
+## Linux Setup
+
+### X11
+
+```bash
+# Debian/Ubuntu
+sudo apt install xdotool
+
+# Arch
+sudo pacman -S xdotool
+```
+
+### Wayland (GNOME, etc.)
+
+```bash
+# Arch
+sudo pacman -S ydotool
+
+# Debian/Ubuntu
+sudo apt install ydotool
+```
+
+Enable and start the ydotool daemon:
+
+```bash
+sudo systemctl enable --now ydotool
+sudo usermod -aG input $USER
+```
+
+Log out and back in for the group change to take effect.
+
+### GNOME Tray Icon
+
+GNOME doesn't show tray icons by default. Install the AppIndicator extension:
+
+```bash
+# Arch
+sudo pacman -S gnome-shell-extension-appindicator
+
+# Debian/Ubuntu
+sudo apt install gnome-shell-extension-appindicator
+```
+
+Enable it via GNOME Extensions app or:
+
+```bash
+gnome-extensions enable appindicatorsupport@rgcjonas.gmail.com
+```

 ## Roadmap
