looks like you have been guided to how to create your about page,

as for the content for the page, just tell about yourself,

if you & I were to meet on the street, what would you tell me about yourself?

hope that helps!

If I'm understanding correctly, you will go to your dashboard, then scroll down on the left column to pages... if you've already started an about page you can edit it, if you haven't started one you can create new page and title it About then put your content into the body..I hope that helps
