 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`
