Before you author a new briefing or report, assemble and organize the ArcGIS maps and any photos, videos, and written text you may want to include. Once you've organized this content, complete the following steps:

1. Open the Briefing Book application on your desktop computer and sign in to your ArcGIS Online organization or Portal for ArcGIS site.
2. Click the New Book button. Enter a name and author for your briefing or report and click the Save Book button when complete. Instead of creating a new item, you can also open an existing briefing or report and click the Copy Book button.
3. Click the Content Page and choose a page layout, then click Add.
4. Add a map and multimedia content to your briefing or report.
5. Click the Contents button to open the Contents panel and switch pages. You can also tap or click on the arrows along each side of an individual page to advance the briefing or report.
6. Save your briefing or report once you've completed your edits. Finally, click the Share Book button and select a sharing option.
