G1nux

Hey guys, I want to create a little mod for my community. It should add some new recipes including items form other mods. The problem is: I've no idea how that works. First I searched on Google and found this tutorial on minecraftforge.net: http://www.minecraftforge.net/wiki/Developing_Addons_for_Existing_Mods It's outdated. Can someone suggest me a new Tutorial or explain me how I can add other (already existing mods) to my development environment? ~G1nux btw I'm from Germany... So please excuse my bad english...
