Go to the 'Add Contacts' tab on your PWI CRM Dashboard. If you would like to add a single contact, simply choose 'Add individual' or 'Add Organization' from the side tab. Then you can add all of the personal and donation information that you have for the contact.
You can also import multiple contacts by going to the Settings page on the PWI CRM Dashboard navigation bar and selecting the Import Contacts tab. This gives you the option to import a .csv file of contacts.
Whenever someone makes a donation, a contact will be created and added to CRM automatically unless they are an existing contact.
