If you don't have a CSV file of people to import, you can add people individually.
People can add themselves by logging into Church Center, registering for an event, joining a group, checking in to an event, filling out a form, or giving a donation.
From the People tab, click Add Person.
Enter the name of the person you'd like to add. The search results will show people who are already in your account.
After typing the full name, select Create a new person and enter their information in the popup.
