At the end, if you include the E-commerce 1.3.1 Maven dependency, the build will fail because E-commerce 1.3.1 requires DX core 6.2.7 or higher, and the tutorial uses 6.2. Mention the (optional) dependency, that it can be resolved by increasing the DX core version in the parent POM file or the E-commerce version in the webapp POM file.

Either a warning before the build command letting the user know that additional Maven dependencies might break the build (with the E-commerce example) or use Alex's drop-drop JS for an optional step during the tutorial: "Want to add your own dependency?"
