I am not sure where you are stuck but here is the process. Unfortunately it is not really detailed but it gives a nice diagram of the system so I am hoping you can see what you need to get off in order to get it out.
Otherwise, let me know the specifics about what is giving you issues and we can go from there. Thanks
