+title: Add blue dot feature highlight to make GKE Clusters more visible to users
+merge_request: 16379
+author:
+type: added

doc/user/feature_highlight.md

+# Feature highlight
+
+> [Introduced][ce-16379] in GitLab 10.5
+
+Feature highlights are represented by a pulsing blue dot. Hovering over the dot
+will open up callout with more information.
+They are used to emphasize a certain feature and make something more visible to the user.
+
+You can dismiss any feature highlight permanently by clicking the "Got it" link
+at the bottom of the callout. There isn't a way to restore the feature highlight
+after it has been dismissed.
