+**ArknightsStudio** is a modified version of AssetStudio designed for Arknights. Based on [AssetStudioMod](https://github.com/aelurum/AssetStudio).
 
 **Neither the repository, nor the tool, nor the author of the tool, nor the author of the modification is affiliated with, sponsored, or authorized by Unity Technologies or its affiliates.**
 
-Since the original repo has been archived, it's worth saying that you shouldn't expect support for newer versions of Unity from this fork. 
-Unfortunately, I can't continue Perfare's work and keep AssetStudio up to date.
