 We force the use of [`pull_request_target`](https://github.blog/2020-08-03-github-actions-improvements-for-fork-and-pull-request-workflows/) as a workflow event to ensure that someone cannot change the CODEOWNER files at the same time as having that change be used to validate if they can merge.
 
+### Extras
+
+You can use this label to set labels for specific sections of the codebase, by having square brackets to indicate labels to make: `[label]`
