Easy installation with script for Linux, EXE installation for Windows. You can download it from Github and use it quickly.
First, it is a bit suspicious when I quote and there are 2 inches of space I can't delete. The next thing is when I go to the download section, I see Lucas Chess mentioned. Third, I suggest people not download anything until you get screenshots showing what you are going to get. When you use .sh files they could be for malicious reasons. Not saying m3tozz is doing anything bad, but red flags are being raised here. In contrast, Hans Niemann's site seems rather innocuous because he is pretty much copying chess.com. So, we can see and compare.
I suggest m3tozz provide some kind of demo/presentation of it before. In fact, the Lucas Chess referred to has a site with plenty of screenshots on their site and in Google images.
