 CLI tool for updating and launching [Project Epoch](https://www.project-epoch.net/) on Windows, Linux and macOS.
 
-## Setup
+If you're a Linux newbie or just looking for a simpler one-click solution, check out [this excellent Lutris script](https://lutris.net/games/project-epoch/) by another community member
 
-### Windows
+## Installing

-Download and extract the latest binary from the [releases](https://git.burkey.co/eburk/epochcli/releases) page or build from source yourself, then copy `epochcli.exe` to a location of your choice. To make it easy, just use the same folder as your Wow game files.
 
 ### 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 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.
+For arm64 macOS (aka M1, M2 etc), I have built an app that handles all of Epoch's setup for you. [Go check it out](https://git.burkey.co/eburk/EpochSilicon)
 
-You can easily install with homebrew or build from source yourself. I dont have time to setup codesigning right now so there are no binaries provided for macOS. For homebrew, do the following:

 1. Run `epochcli`. You will be taken through a setup process that configures the program and creates a config file at `$HOME/.config/epochcli/config.toml`

+2. You can now use `epochcli` as a standalone updater, but it can also act as a launcher based on your configuration. You can always run `epochcli -c` to redo the configuration, or edit the config file manually
+3. By default, `epochcli` will delete any non-standard patches. This can be disabled by changing the configuration file's `RemoveUnknownPatches` value to `false`
