i'll try and help. if in the readme with those files stats it replaces thing you drop all the files to your data folder inside morrowind and your done. if it say's it's modders resource you will have to do the same but you will have to open up the construction set and add the objects yourself. you could have a look at this site http://www.mwmythicmods.com/toolsmod.htm#Tool_m_rt it explains a lot on how to import custom objects to the game
