-If the answer to those is "yes":
+# Emacs with native compilation ("gcc") and Wayland support
 
-- Do you want to use Emacs with native compilation enabled?
-- Do you want to use Emacs with Wayland support?
-- [Optional] Are you using Arch Linux?
+Because [native-comp](https://www.emacswiki.org/emacs/GccEmacs) is
+[fast](https://akrl.sdf.org/gccemacs.html),
+[Wayland/GTK3 support](https://github.com/masm11/emacs) means optimal HiDPI,
+cleaner/simpler dependencies, no XWayland, etc. This package is also a
+convenient way of using the "devel" version of Emacs without having to compile
+it yourself.
 
-Then you might be interested in this repository. If you want all of those but
-you are not using Arch Linux, you can still go to the
-[release page](https://github.com/mpsq/emacs-gcc-wayland-devel-builder/releases)
-and grab the latest binaries.
+Note: we do not patch / amend or modify Emacs directly, this is a _vanilla_
+binary of Emacs with specific compilation flags.
 
-# What is this?
+# How to get it
 
-This repository is just a factory that creates Emacs binaries for `x64` so you
-don't have to do it yourself. The base Emacs branch that this repo builds can be
-found at [github.com/flatwhatson/emacs](https://github.com/flatwhatson/emacs).
+## Arch Linux
 
-Arch Linux users can install the binaries directly from `AUR` using the
-[emacs-gcc-wayland-devel-bin](https://aur.archlinux.org/packages/emacs-gcc-wayland-devel-bin/)
-package.
+Use the `AUR`
+[package](https://aur.archlinux.org/packages/emacs-gcc-wayland-devel-bin/):
 
-# Why?
+```sh
+yay -S emacs-gcc-wayland-devel-bin # or any other AUR helper
+```
 
-Because [native comp](https://www.emacswiki.org/emacs/GccEmacs) is
-[fast](https://akrl.sdf.org/gccemacs.html),
-[wayland support](https://github.com/masm11/emacs) means optimal hidpi support,
-and you now have a convenient way of using the "devel" version of Emacs without
-having to compile it yourself.
+## Others
+
+If you are not using Arch Linux, you can still go to the
+[release page](https://github.com/mpsq/emacs-gcc-wayland-devel-builder/releases)
+and grab the latest binaries.
+
+Based on demand, I might add compiled packages for other Linux distributions, if
+you are interested, let me know in the
+[issues](https://github.com/mpsq/emacs-gcc-wayland-devel-builder/issues).
