First you find it on a safe site such as M&B repository. If you're concerned if the site is safe or not ask this forum and get updated anti-virus software (of course only one at a time on a computer). There are several ways that it downloads. The magically easy way is when it allows you to save it right to the modules folder. The most often for me is giving me a complex file such as RAR; you will need to extract all files to the modules folder. Sometimes you get just a plain folder in the downloads folder; for this just open up the two and do the old fashioned drag and drop. If you're lucky, certain mod folders are actually install packs, and they will do everything for you. I have not had any other way of getting mods, so I hope that is all. If you're wondering where the modules folder is, it's under "my computer," "local disk C," "program files," then "Mount&Blade" and it should be right there. Make sure that the mod folders are inside their own folder that they came in, inside the modules folder.
