+# Geoffrey Architecture
+
+**Note: Geoffrey V3 is in early development, and its design is likely to change.**
+
+![Geoffry Architecture](figures/arch.svg)
+
+## Database
+The database is the core storage of Geoffrey. All models will be stored here. It is tightly
+coupled with the GeoffreyAPI. 
+
+## Geoffrey API
+The API provides the main logic to how models are manipulated in the Database. It is split
+into two parts, the Command API and Model API.
+
+### Command API
+This API will expose a set of commands that can be run to preform tasks in Geoffrey. The goal
+is to keep all the command logic here so the command front-end are simpler to create.
+
+### Model API
+The Model API will provide a strict access to the underlying models of Geoffrey. It is
+more suited for web interfaces or operations that do not need to be constrained by commands.
+
+## Front Ends
+The currently planned front ends are a Bukkit Plugin, a Discord Bot and the Web Interface.

+# Geoffrey: A Location Database for Minecraft Servers
+
+Geoffrey was created to be an information source for base and shop locations on Minecraft severs. Geoffrey can track 
+bases, shops, items for sale, tunnels, towns, public farms and more!
+
+This is the third ~~complete rewrite~~ version of Geoffrey. V3 focuses on improving the API,
+adding new features, and moving to Rust.
+
+This version is still very early in development and things are very likely to change.
+
+## Project Layout
+* [`geoffrey_models`](./geoffrey_models): Models used throughout Geoffrey, split into their
+own library for reuse.
