+# Developing
+
+## Setup
+
+Clone the repository and run `git submodule update --init --recursive`.
+
+See [here](https://docs.godotengine.org/en/latest/tutorials/scripting/gdextension/gdextension_cpp_example.html#doc-gdextension-cpp-example) on how to create and compile GDExtension libraries.
+
+## Building for Testing
+
+To compile for Linux, run the following commands.
+Compiling for other platforms works analogously.
+
+```sh
+$ scons target=template_debug platform=linux optimize=speed_trace arch=x86_64 -j8
+$ scons target=template_release platform=linux optimize=speed arch=x86_64 -j8
+```
+
+Output files are saved to `demo/addons/ropesim/bin/`.
+
+The repository contains utility scripts `compile_debug.sh/bat` and `compile_release.sh/bat` for convenience.
+Additional SCons arguments can be appended to the script call.
+
+## Code Analysis
+
+Use `./run_clang_tidy.sh` to run `clang-tidy` checks for the project.
+
+This requires an existing `compile_commands.json`, which is automatically generated during build.
+It can also be generated by specifying the `compiledb` target to SCons, e.g. `./compile_debug.sh compiledb`.
+
+
+## Production Builds
+
+The extension is built automatically using Github Actions for different platforms and targets.
+See [build.yml](.github/workflows/build.yml).
+
+This workflow automatically runs on push and pull request events and outputs a zip that can be easily distributed and installed.
