-### Primary button plus secondary action menu
+### Displaying primary and secondary tasks
 
-This [menu](../button-menu) is made up of multiple menus. The first consists of just one button and is exposed because it's a primary action. The second menu consists of two secondary options, which are placed within a drop down menu.
+You can use the [button menu](../button-menu/) alongside a [GOV.UK button](https://design-system.service.gov.uk/components/button/) (or link) to show tasks of differing importance which relate to the identity bar. This code has correct spacing and creates a better user experience for people on mobile devices.
