Need help with word doc

How do you format the page in Microsoft Word to make a tri-fold pamphlet? I'm so clueless....I hate computers

Thanks!

Open new doc and go to 'Format' in the menu bar click on 'Columns' select three columns option and then enter the width you want the columns to be. If you are going for portrait page set up enter 2.84 for column width, if you are going for landscape page set up enter 3.67.

Good luck.
