Welcome to WikiTree. The "biography" part of your profile is probably the most important thing you will add to WikiTree. Peter gave you the technical step...but what are you going to put there? You can add your personal history, your likes and dislikes, the style you will use as you add other profiles, why you came to WikiTree in the first place, your genealogic goals, your hobbies, what your family name means, your ethnic background, your brick walls that you are working on (family history you just cant find answers to yet), the black sheep in your family, the famous people in your family...the list goes on and on and on. Have fun and be sure to ask for help right here on G2G when you need it. All the best!
