- rename the file as ".... .inc" when you are done!
- save it
- maybe you shoul save the original file somewhere else so that you can replace it in case something is not working
now you will have Durin, Thor and Thrain in every War of the Ring campaign when you choose dwarves.
This can be done with every unit/ hero in the game, you just need to find his defined name. You can add Mumakils, Sauron, whatever you want into every faction you want.
Have fun!
