Creating a story map basically involves uploading a spreadsheet to a site that will plot it for you on a map (in this case ArcGIS Online), and choosing a specific template for your display. If you know a bit of HTML, you can edit the way your text displays, but this isn't strictly necessary.
Story maps are exactly that – maps that tell stories. While , in a sense, every map tells a story, story maps integrate images, maps, text and video to bring a story to life visually. Their visual presentation and interactivity allow users to learn about your topic in a new way.
