-# Evolve Die Repeat TODO: The name is a work in progress

-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
-```
