+Far Glitch Land
+===============
+
+This mod adds glitchy-looking lands at the edge of the world. It is inspired by [Minecraft's Far Lands](https://minecraft.wiki/w/Far_Lands).
+
+## Configuration
+
+To configure this mod, use the Settings menu > Content: Mods > Far Glitch Land. The configuration is _not_ saved per world, but saved globally, and affects new world generations.
+
+|          Name          |        Description        |  Default |
