Once on the page, you will need to subscribe to the NFHS Network by clicking the "subscribe" button near the top right of the page. Cost is $10.99 per month for a monthly pass or $69.99 for a yearly pass. A portion of these fees are returned to the district.
Once subscribed, you can follow NFHS Network by clicking the "follow" button also at the top right. This will make sure you see all of the games scheduled for NFHS. Subscribers will also be able to access the streams "on demand" after the games have ended.
Viewers also have the ability to stream and upload for "on demand" viewing certain "non-athletic" events. These can be set to be accessed WITHOUT a subscription.
