I created a block diagram to explain the gameplay of my project. I did it in diagrams.net. I really like how it looks and it makes my README.md way better. I also fixed file formats of some images, because github doesnt suppord PDFs in the README and i had a hard time exporting .svg files. I later realised that i can put a black rectangle behind my PCB svg and now the constrast is really good and i can see everything clearly.
