First, select 'Add Contacts' from the 'Contacts' drop-down menu then fill in all the required fields.
If you don't want to add this new contact to an existing list then simply click 'Add to New List'. You can also add a new tag for this contact by clicking 'Add New Tag' to the right of the Tags field.
Note: This is where you will be able to fill in the custom fields for the contact.
