It's not really a question of should write description, but you must write a description.
Apart from being a requirement for uploading, you have uploaded an .exe file (within a zip), and are expecting users to downloaded and run that exe. The internet can be a nasty place, and our members should not have to risk anything to get the mod if they want it. Of course they don't know if they want it because there is no description.
I happen to know that this is a clean file, and it's just an installer when you choose the destination folder for the mod. I know what files are in this mod.
So please add a description, and I would be grateful if you would simply archive the files in a rar, zip, 7z etc (no .exe). and re-upload (update) replacing this file. Otherwise the mod will have to be removed,
Cheers
