+# project-kyoku
+
+I am just trying to create a rhythm game inspired by project-diva
+
+### Initial setup
+
+- Make sure you have a compiler supporting c++17 and cmake
+- Make sure you have [sfml](https://www.sfml-dev.org/) installed, either static or not, just make sure to edit impl/ CMake file, you'll see it.
+- Now clone it
+```
+git clone https://dev.udongein.xyz/NaiJi/project-kyoku
+```
+
+- Go to the project folder
+```
+cd project-kyoku/
+```
+
+- Now build it!
+```
+cmake CMakeLists.txt -B ./build
+cd ./build
+make
+```
+
+### Conventional commits
+
+This project follows [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/). 
+
+`<type>(optional scope): <description>`
+
+Example: `feat(classic-mode): Implement something great`
