What is the Quark mod?
Quark is a mod for Minecraft. It aims to create an experience akin to the "vanilla" experience, by having a very simple motto: anything that would be added to Quark could also be added to the default game without compromising its gameplay style. Quark currently has 130 features to spice up your game, all of which fitting the previous motto.
To that end, every feature added to Quark is simple and small. Hence the name of the mod, Quark, as a Quark is a very small thing. Quark is a Modular mod. Which means that its features are split within various modules. All of the modules can be disabled, and all the features can also be disabled individually if one wants to. Many of the features even have extra configuration options.
The mod features ingame configuration via the Mod Options menu. Most features can be toggled from inside the game, others require a world reload, it depends on the changes they make. Any features that add new explicit content, such as items, blocks or entities, will require a reset.
