In plain English

This repository is an unofficial distribution of osu!lazer, the next-generation client for the rhythm game osu!. Osu! is a free music game where players click, tap, or slide to the beat of songs. The lazer version is a complete rebuild of the original client using modern technologies, with the stated goals of better performance, a cleaner interface, and an improved gameplay experience. The README describes features including cross-platform support across Windows, macOS, and Linux, improved skinning and customization options, built-in multiplayer and spectating, and support for beatmaps and storyboards. Beatmaps are the community-made song levels that players download and play. The README does not go into detail about what specifically changed from the older client. Getting started involves downloading a zip file from the releases page, extracting it, running the executable, and logging in with an existing osu! account. The minimum system requirements listed are a modern dual-core processor, 4 GB of RAM, and a graphics card that supports OpenGL 3.3. The README includes a disclaimer noting that this is an unofficial distribution, not the official project. The official osu!lazer is developed by a team called ppy and lives in a separate repository. For the most up-to-date official builds, the README directs users to the official repository instead. This repository appears to be a repackaged or mirrored distribution of that official open-source project.
