Magic Forums

First I would like to say hello, and thank you for reading.I am new to the website, and I would like to know how to create a familiar.I have been reading alot of forums on the subject,but sadly I am still confused.People say that when you create a familiar you need to feed it energy,but how do you do that? How do you create a familiar, and how do you feed it energy so it won't disappear?If you can give me a specific answer that would be much appreciated. -Thank you
