I'm not sure if I should tell you, because if you don't know how to do this your Add-on might suck...
Well, if it does it'll be fail bin'd, so:
Right-click on your Desktop and select New > Zip folder/file/something (I use Winrar, so I don't recall the exact name)
Name it using the file prefix rules for add-ons (Script_Add-on_name, Weapon_Add-on_name, etc.)
Put the files into the folder.
Upload it to a file hosting site such as Mediafire (Make sure you test it first.)
Post.
