+![MR widget - Optional Code Owners Sections](img/optional_code_owners_sections_v13_8.png)
+
+If a section is duplicated in the file, and one of them is marked as optional and the other isn't, the requirement prevails. 
+
+For example, the code owners of the "Documentation" section below will still be required to approve merge requests: 
+
+```plaintext
+[Documentation]
+*.md @root
+
+[Ruby]
+*.rb @root
+
+^[Go]
+*.go @root
+
+^[Documentation]
+*.txt @root
+```
+
+Optional sections in the code owners file are currently treated as optional only
+when changes are submitted via merge requests. If a change is submitted directly
+to the protected branch, approval from code owners will still be required, even if the
+section is marked as optional. We plan to change this in a
+[future release](https://gitlab.com/gitlab-org/gitlab/-/issues/297638),
+where direct pushes to the protected branch will be allowed for sections marked as optional.
+
