 CLI tool for updating and launching [Project Epoch](https://www.project-epoch.net/) on Linux & macOS.
 
-## TODO
+## Setup Instructions
+For Linux, a `wine` prefix with `dxvk` installed is sufficient, or you can use something like Lutris or faugus-launcher without the launcher functionality in `epochcli`
 
-- improve config generation
+For macOS, the [Kegworks Wineskin port](https://github.com/Kegworks-App/Kegworks) works great (tutorial coming in the future...)
-- add ability to launch Epoch after an update
 
-## Instructions
+1. Install `epochcli` by either
-For Linux, a `wine` prefix with `dxvk` installed works great, or you can use something like Lutris or Faugus-launcher
+   1. Downloading the latest binary from the [releases](https://git.burkey.co/eburk/epochcli/releases) page

-2. Install `epochcli` by either
-   1. Download the latest binary from the [releases](https://git.burkey.co/eburk/epochcli/releases) page 
    2. If you have the `go` toolchain installed, you can run `go install git.burkey.co/eburk/epochcli` to install to your `$GOROOT`
    3. Compile the source yourself
-3. Run `epochcli` once. This will create a config file at `$HOME/.config/epochcli/config.toml`. Update the variables with the appropriate information
+2. 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`
-4. Run `epochcli` again. It will download the patch files from Epoch's servers to your Wow directory and start the game. You can also pass the -u switch to only update if you use a launcher like Lutris, etc
+3. You can now use `epochcli` as just a standalone updater or also a launcher based on your configuration. You can always run `epochcli -c` to redo the configuration or edit the config file manually
+
+## Usage
+```
+> ./epochcli -h
+  -c    Runs config configuration step. Overrides the config file
+  -h    Print help
+  -u    Ignore EnableLauncher setting in config and only runs an update. Does nothing if EnableLauncher is false
+```
