First you need to extract the files from the .jar file the mod is originally in. To do this, use a program such as 7-zip to create a folder. Inside this folder should be another folder called 'lotr' and another called 'assets' (which contains all the texture files, sounds and speechbanks etc.). Inside the 'lotr' folder will be a folder called 'common'. Inside this will be many sub-folders and .class files, which are the java code files for the mod.

Use |this software to open the .class file for the mod, and then you can see the code, which is not that easy to understand.
