How do you write a essay of an remembered event in MLA format?

I have a paper due on remembered event and my teacher had instructed us to write it in MLA format. Needles to say she has not taught us about what MLA is at all. She said you have a guide book on it and I can't make nothing of the book at all. She is a book writer so it has to be almost perfect for her. Nothing is good enough he thinks we should know it all because it is college english and I have been out of school 11yrs and never had to do a paper in that MLA format in High School. I NEED HELP
