Hi Patty!
That's a good question. There's a few ways you could share Rise 360 content with learners.
One way is to simply host it on a website, as you mentioned. You just export the content to HTML5 format, it created a zipped folder you can upload to your FTP or server and then just send the URL link to learners.
Another option is some organizations use a Learning Management system (LMS) if they need to track and report on learners (for example if they need to know who took the training, who passed, who failed, etc.) . In that case you would export the content for LMS. Either way, its a simple process that just takes a few clicks.
Here's more information on how to export Rise content:
