+# Terrain Editor Module
+
+- Godot Engine Module for Terrain Generation
+- Multi-threaded
+
+## Architecture
+
+`Terrain` (terrain.h/cpp) responsible for managing and dispatching mesh generation tasks to its pool of threads. Attempts to stay as light as possible outside of load-time.
+
+`TerrainMeshChunk` (terrain_chunk.h/cpp) the substance of the terrain. Contains functionality to generate meshes from terrain modifiers and data to display and collide with a terrain. Independent from other chunks. Dependent on terrain.
+
+`TerrainModifier` (terrain_modifier.h/cpp) Core of the interface, 3D markers that designers place to define how the terrain should be generated.
