Trying to install the CATS plugin (https://github.com/GiveMeAllYourCats/cats-blender-plugin) I extracted it and it was a bunch of confusing files, no .exe files in sight. I downloaded this as a zip. What do I do?
I think you do not need to unzip the archive. Go to Edit > Blender Preferences, then choose Add-ons section from the sections on the left side and press "Install an add-on" button on top, browse for your zip file, choose the file and press "Install Add-on" button on the bottom next to Cancel button, after add-on is installed you need to enable it.
