-Cacao is a UI framework for Fabric/Minecraft mods based on Apple's [Cocoa](https://en.wikipedia.org/wiki/Cocoa_(API)) UI toolkit.
+## Architecture
+### Screen
+A [CacaoScreen][] is the object that acts as the interface between Minecraft GUI code and the Cacao framework.
+
+The CacaoScreen draws Cacao views on screen and passes Minecraft input events to the appropriate Views. The CacaoScreen
+owns a group of [Window](#window) objects which are displayed on screen, one on top of the other.
+
+[CacaoScreen]: https://git.shadowfacts.net/minecraft/ASMR/src/branch/master/src/main/kotlin/net/shadowfacts/cacao/CacaoScreen.kt
+
+### Window
+A [Window][] object has a root [View Controller](#view-controller) that it displays on screen.
+
+The Window occupies the entire screen space and translates events from the screen to the root View Controller's View.
+It owns a Solver object that manages layout constraints. The window also handles screen resizing and re-lays out the
+view hierarchy.
+
+[Window]: https://git.shadowfacts.net/minecraft/ASMR/src/branch/master/src/main/kotlin/net/shadowfacts/cacao/Window.kt
+
+### View Controller
+A [ViewController][] object owns a view, receives lifecycle events for it, and is generally used to control the view.
+
+Each View Controller has a single root [View](#view) which in turn may have subviews.
+
+[ViewController]: https://git.shadowfacts.net/minecraft/ASMR/src/branch/master/src/main/kotlin/net/shadowfacts/cacao/viewcontroller/ViewController.kt
+
+### View
+A [View][] object represents a single view on screen. It handles drawing, positioning, and directly handles input.
