You must download the mod file (packaged as zip or rar), open it using a program (winzip, winrar or something), and unpack the contents into your mods folder. The folder is in Dominions II\mods after you have patched the game and run it once, or you can just add a new folder named mods if one doesn't exist already.

After that, you have to enable the mod by going to the Preferences - Mod Preferences, and choose the mod you want to enable. Any pretenders done after enabling the mod will be done with the mod enabled, and any games started will be using the mod. If the mod changes costs of pretenders, you should always create a new pretender before using the mod. You cannot change a game to use or not to use a mod after it has been started.
