From the home screen, click on the Wellness Program "See all" link . You can now view programs starting soon categorised into Programs or use the search bar to find a specific event by name or ID.
You can now click on an event to view the information about this specific program. You'll be asked to pay for the event (note that some events are prepaid by the host but you will still be required to go through the checkout process at $0).
Once you have checked out, you'll now be shown the Program home where you can see what items you have to complete in the Todo. You can also view information on the Sessions, see who is in your Group, and post into the Feed.
Note: Some programs require an assessment to be completed before starting. This will appear in your Todo list.
