Спасибо за оперативный ответ. Сапожки уже нашел ))

Не ясно что нужно сделать и какие файлы поместить в папку override и где эти файлы взять

Just subscribe and the items will be downloaded into an override folder when you play the game. You do not need to copy or install anything. The description text above explains where you will find them in the game. If you have already been playing and gone past a location then you can use the console to add an item to your inventory manually.

This is included in my Complete Makeover mod, so if you already have that installed and only use the Nasher items when playing the OC then you do not need to subscribe to this.

If you choose to use the console to add the items rather than finding them during the course of the game then you may want to reenable achievements by editing your save file globals.xml changing the 1 to 0 (zero) in these lines (credit to Aldroen):
