+# Example Mods
+This is an example of a mod that can be built using the modding SDK.
+
+* **Expanded Creative Mod**: This specific mod adds even more items and blocks to the Creative Inventory. It was originally by [@Bigjango13](https://github.com/bigjango13).
+* **Chat Commands Mod**: This specific mod makes an chat message starting with a ``/`` handled by the MCPI API.
+* **Recipes Mod**: This specific mod demos custom recipes.
+
+## The SDK
+The modding SDK is a collection of exported CMake targets that allows anyone to create their own MCPI mod!
+
+The SDK is copied to ``~/.minecraft-pi/sdk/lib/minecraft-pi-reborn-client/sdk/sdk.cmake`` whenever MCPI-Reborn is started.
+
+## How do I use this?

+mkdir build
+cd build
+cmake ..
