Charm is a Forge Mod for Minecraft 1.12, inspired by Quark, that adds to the vanilla experience of Minecraft without drastically changing its gameplay. Charm does not require Quark to be installed but is designed to play nicely with it and extend some of its features.
It’s a modular mod in that you can turn on or off any of the mod features via the config file.
Charm for Minecraft 1.12 is no longer being actively maintained due to lack of time. Serious bugs will be worked on when time permits. Charm is being developed for Minecraft 1.14+ and you can find the documentation here.
You need to install the Java Edition of Minecraft and then the correct version of Forge for the version of Minecraft you want to play. Once you have done this, drop the Charm jar file in your mods folder and start the game.
After the game starts for the first time, you can edit the charm-common.toml file (in the config folder) to change things about Charm. Each of Charm’s features can be disabled or tweaked to fit your playstyle.
