+## Overview
+
+This is a lerna/monorepo setup that is split up into types, native, core and ui packages.
+
+- packages/ui: pulls in everything from core and native and re-exports it. This is what any user will install to use this Library
+- packages/core: Non-native, javascript components go here. These are components that work perfectly across web, ios and android without any adjustments
+- packages/native: Native components that rely on expo/react-native modules likes `expo-av` and `@expo/vector-icons`. This houses our AudioPlayer and Icon components because the current version requires modifications to work well on Web
+- packages/types: Shared typescript types and SEED_DATA types which is how we build the translation layer for Draftbit
+
+### SEED_DATA
+
+You'll notice that most components will have `SEED_DATA` at the bottom of their files. This is how we incorporate components and props into Draftbit's property panel.
+
+The object at the bottom maps one to one to what the UI will look like in the panel. Here's an example of the "View" component:
