+Advent of Code project
+
+## Requirements
+
+  - [cmake](https://cmake.org/) for C++
+
+## Development
+
+This project has support for different languages.
+
+### C++
+
+There are different ways to setup this project, using `ninja` or Visual Studio.
+
+To use `miniaudio` to play audio on host machine use the flag `-DUSE_MINIAUDIO=ON`.
+
+```sh
+cmake -S . -Bbuild -GNinja -DCMAKE_BUILD_TYPE=Debug
+```
+
+Use `ninja` to build.
+
+
+```sh
+ninja -C build
+```
+
+Symlink `compile_commands.json` to root directory for `ccls`/`clangd`.
+
+```sh
+ln -sfn ./build/compile_commands.json .
+```
+
+**Windows (requires admin)**
+
+```sh
+New-Item -ItemType SymbolicLink -Path "compile_commands.json" -Target "./build/compile_commands.json"
+```
+
+### Visual Studio
+
+```sh
+cmake -S . -Bbuild
+```
+
+Open either the visual studio project in the build directory or use
+
+```sh
+cmake --open build
+```
+
