In order to connect your twitch account to the game and display the chat, you will need both a twitch account and an access token. See Prerequisites for more info.

After installing the mod, you will need to start the game once to generate the Twitch.json config file.

Once the game has started, close it.

Now that the Twitch.json file has been generated, you will need to edit it with a text editor (the default notepad will work just fine).

The file can be found in the <game directory>/Distance_Data/Spectrum/Plugins/<plugin directory>/Settings folder.

The file should look like this:

{
    "Channel": "<channel id>",
    "Token": "<access token>"
}

Once everything is done, you can start the game.
