Hello, this is how your index.html should look like after adding the line which makes it possible to load the mods.
The process is pretty much the same for both games, just be sure to read the Mod Scope of a mod to ensure that the mod/s will work for the Fear & Hunger game you want to mod.
If you have any other question feel free to comment again and i'll try to get back to you. Have a nice day!
