I need some help to make a layout for my story. I would like it to look like a diary with a few points that needs to be there

A chapter title
A def. of the word in the title
An introduction to how that side in the diary should work
A part to where the story in itself is posted. 

The story it's for is here if you need some sort of inspirtation to what it goes for ^^

Comment here or pm me if you are interested in helping me out and for more specific details xD
