If you have a new Jamf Now account, we suggest following the steps in the Jamf Now documentation Getting Started guide to get your Jamf Now instance setup.
The guide provides links to progress through the steps you need to take in Jamf Now before enrolling devices for management:
Integrating with Apple Push Notification Service
Integrating with Automated Device Enrollment in Apple Business Manager or Apple School Manager
Integrating with Volume Purchasing in Apple Business Manager or Apple School Manager
Creating blueprints
Note: It is not obligatory to use Automated Device Enrollment or Volume Purchasing from Apple Business Manager or Apple School Manager, but doing so provides more management capabilities.
