Free Games Notifier¶

discord-free-games-notifier is a bot that notifies a channel whenever there's a free game on Steam or Epic Games.

There is an official image for this service that we'll use: ghcr.io/moonstar-x/discord-free-games-notifier.

Pre-Installation¶

We'll create a folder in the main user's home where all the service's data will be saved.

mkdir ~/services/discord/discord-free-games-notifier
