How to lighten my hair with lemons?

Can someone please tell me how to lighten my hair with lemons! I have medium light brown. And I need the exact steps. For example how many lemons to use, How much water to use (If I need), How long to stay in the sun, What to wash the lemon juice out with, ect.

I would REALLY be grateful if you answer this question!

i did this last week, and its very very simple.

cut one lemon in half, and squeeze out the juice into like a bowel or anything like that, and just sort of pour it into your dry hair and brush it through, then go out in the sun for about 5 hours so go out to see some friends, hang out in the park or something. wash your hair that evening i suppose. I have already got comments on my hair and how light it has got. (:How to lighten my hair with lemons?
I hope you know that Lemon Juice barely works on blond hair. In fact, The acid in it does more damage to your hair, then it would lighten it.
use sun-in. it's way better. hope this helps. :)
