 ## Installation
 
-**[Download the latest binary from the release section](https://github.com/phil294/AHK_X11/releases)** (the file called `ahk_x11.AppImage`). Make the downloaded file executable ([how?](https://askubuntu.com/a/484719/378854)) and you should be good to go: Just double click it *or* run it in the console without arguments (**without** sudo).

+<details><summary>Alternative for Arch Linux users: AUR package</summary>There's an <a href="https://aur.archlinux.org/packages/ahk_x11">ahk_x11</a> and an <a href="https://aur.archlinux.org/packages/ahk_x11-git">ahk_x11-git</a> package available, kindly maintained by Freso. Note: With these packages, contrary to the AppImage one, if you use the script compilation feature, the resulting binaries will *not* be portable across different Linux distributions! Alternatively, you can also build the AppImage from source if you have Docker installed (see "Build from source" below)</details>
 
 Prerequisites:
 - X11 is the only dependency. You most likely have them already. Wayland support would be cool too some day.
