-# 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`
