As you are adding content to a topic or article, you can obtain a live preview of your topic or article at any time by clicking on the 'Preview' button on the top right of the screen.
When you preview your topic or article, you see it as an explorer does. You will need to answer questions, completed assessment, watch Narrations and so on.
As you edit your topic and make changes, simply return to preview to see how they look (if you already have preview open in another tab, you may need to refresh your screen to see the changes).
You can use the drop-down menu on the Preview button to 'Reset Preview' at any time. This will delete your progress and contributions to the preview and put it back to the start (a good way to check out the flow of your topic or article for new explorers).
