There are two ways to add a contact into the database. From the contact list page you can click on Create New, or from any page you can click Quick Add.
Creating a new contact will open up the info box below:
You can enter in as little or as much information as you wish. You can always come back to the contact and add more at a later time. There are sections for you to add information relative to family members, interests, important dates, and any additional information you may have.
