+# Godot GLTF import and export module
+
+In a nutshell, the GLTF module works like this:
+
+* The [`structures/`](structures/) folder contains GLTF structures, the
+  small pieces that make up a GLTF file, represented as C++ classes.
+* The [`extensions/`](extensions/) folder contains GLTF extensions, which
+  are optional features that build on top of the base GLTF spec.
+* [`GLTFState`](gltf_state.h) holds collections of structures and extensions.
+* [`GLTFDocument`](gltf_document.h) operates on GLTFState and its elements.
