I recommend you to visit the tutorials as well as http://www.dreamviews.com/

To get lucid dreams, you first need to recall your dreams. As a quick start I could say that you should write down anything you remember from your dreams. If you wake up in the middle of the night and remember something, you must write it down as soon as possible... that will help you to recall your dreams and many more things (such as finding the clues that will notify you that you are dreaming) In addition, you will perform a WBTB (wake back to bed) which increases dramatically the chances to LD. But you need recall or you won't even remember your LD. So go ahead and check the tutorials and that improving your dream recall. I just made an extremely shot brief summary to give you an idea.
