Creating an Immersive section:

But they’re worth the effort! The tutorial above is useful.
Creating a Map:
You can use other public maps in ESRI Story Map, but it's good to create your own. Follow this tutorial to do so: learn.arcgis.com/en/projects/get-started-with-arcgis-online/lessons/create-a-map.htm
Sharing your Site:
After you’ve tested the software, then “storyboard” your website. This means that you gather all the materials for your argument—your text, your images, your maps—and create a visual outline or storyboard. Then input all your materials and test your output, saving frequently, and finally share it with the public (hit the globe icon) when you're done.
Be absolutely careful about sources! You cannot use other people’s images, maps, or words without careful attribution. Photographers are especially firm about image theft—so you must use freely available images, not copyrighted images, and always include a link and the photographer’s information.
