PREAMBLE="# Disclaimer

Thank you for your interest in osu!lazer.

These pre-releases are provided for people interested in following development and getting a sneak-peek at what we're working on. osu!lazer is *not* yet intended to be a playable alternative to [osu-stable](https://osu.ppy.sh). If it doesn't work for you and you are unable to submit a fix, please check back at a later date!

More information is available in the [project readme](https://github.com/ppy/osu). Daily dev updates are also [posted on my blog](https://blog.ppy.sh)."
