+## Up for adoption

+Hello there! Are you interested in mesh simplification and would like to take this package further?
+
+I'm currently looking for someone to take over this repository since I feel like I'm not the right person to do it, nor do I have enough time to spend on it. Or if you'd just like to be a maintainer. Preferably someone with a better knowledge and interest in mesh simplification.

 ## Compatibility
 
 Because this project is now using Unity packages, you should use a Unity version from 2018.1 and beyond.
