+Linux notice
+---
+- osu! stable build tested on [osu-winello script](https://github.com/NelloKudo/osu-winello/tree/main) with arch linux 2025.03.01 (latest confirmed that all works)
+- If you're using custom wine prefix with wine cwd breaking (your cwd is showing windows path instead of full linux one) please set `TOSU_OSU_PATH` in your bash/zsh profile (example `TOSU_OSU_PATH=/home/kotrik/.local/share/osu-wine/osu!`)
+- osu! lazer builds tested on AppImage from official osu repository and flatpak image
