 - In `@arcgis/map-components@next`, `Zoom` and other navigation components have been removed as defaults in the `arcgis-map` and `arcgis-scene` components. The only default component will be `Attribution`. All others need to be added manually, for example:
 
 ```html
-  <arcgis-map basemap="dark-gray-vector" center="-90.1994,38.6270" zoom="4.5">
+  <arcgis-map basemap="dark-gray-vector" center="-90,38" zoom="5">
       <arcgis-zoom position="top-left"></arcgis-zoom>
       <arcgis-home position="top-right"></arcgis-home>
   </arcgis-map>
