+            It looks like your proposed **_Pull request title_** needs to be adjusted.

+
+            #### Pull request title naming convention
+
+            Our PR title name taxonomy is `type: Subject`, where **type** is typically
+            *feat*, *fix*, or *chore*, and **subject** is a phrase (proper noun) that starts with a capitalized letter.
+            The *chore* type usually has a subject that starts with an action verb like *Add* or *Update*.
+            Examples: `feat: Admin portal login`, `fix: Divide by zero bug in SMA`, and `chore: Update user docs`.
+            See the [Conventional Commits specification](https://www.conventionalcommits.org) for more information.
