I'm trying to clone the kotlin project to contribute but I'm not quite sure if I'm doing that part right. Tried to read the README for hints but there was really nothing on cloning. Cloning it takes forever in intellij git, and when I download the project as a zip and I try to open it, it crashed my file explorer. What reason would there be for that? Am I missing something? I know the project is huge but what exactly am I supposed to do? I've cloned it before but it's like I can't for some reason my computer just doesn't like it.
