 ## Installing
 
 ### Linux
+
 A `wine` prefix with `dxvk` installed is sufficient, or you can use something like Lutris or faugus-launcher and just use `epochcli` for updating.
 
 Download and extract the latest binary from the [releases](https://git.burkey.co/eburk/epochcli/releases) page, build from source yourself, or use homebrew from the macOS instructions to install.
 
 If you are an Arch Linux (or derivative) user, you can use the provided [AUR package](https://aur.archlinux.org/packages/epochcli) to install
 
+A tutorial for the full setup of Epoch on Arch Linux [can be found here](https://burkey.co/posts/epoch-linux/)
+
 ### macOS
 
 For macOS, I've found the best way to run Wow is in a Parallels Win 11 VM. Kegworks, Codeweavers, etc crash when the game starts up and I have not found a good solution so far. Any suggestions would be welcome, see my contact information below. I currently use a Parallels VM and run the Windows version of epochcli inside the VM as an updater and launcher.
