Assuming you read my tutorial you should at least have specific questions regarding it. It might help to ask about the details you do not understand. (somebody else could then try to use different words for the section that is a mystery to you)
Other helpful tutorials are also found in the FAQ.
It might be a good idea to work through the how to make a symbol and how to make a footprint tutorials even if this means making a symbol/footprint for a part that you do not need right now. This should give you an idea of how everything can be done.
