+This is currently quite empty.
+
+## C++ setup
+From anywhere in proejct:
+```bash
+git submodule update --init --recursive
+```
+
+In `thirdparty`:
+```bash
+godot --headless --dump-extension-api
+```
+
+To compile the cpp extension, run this from `thirdparty/godot-cpp`:
+```bash
+scons platform=linux target=template_debug generate_bindings=yes custom_api_file=../extension_api.json -j8
+```
+
+Finally, to compile and extern local `.cpp` files, run this from `thirdparty`:
+```bash
+scons platform=linux target=template_debug -j8
+```
