+Browser Performance Testing has gone through several changes since its introduction.
 In this section we detail these changes and how you can run the test based on your
 GitLab version:
 
+- In 13.2 the feature was renamed from `Performance` to `Browser Performance` with additional
+  template CI/CD variables.
 - In GitLab 12.4 [a job template was made available](https://gitlab.com/gitlab-org/gitlab/blob/master/lib/gitlab/ci/templates/Verify/Browser-Performance.gitlab-ci.yml).
-- In 13.2 the feature was renamed from `Performance` to `Browser Performance` with
-additional template CI/CD variables. The job name in the template is still `performance`
-for compatibility reasons, but may be renamed to match in a future iteration.
 - For 11.5 to 12.3 no template is available and the job has to be defined manually as follows:
 
-```yaml

 Upgrading to the latest version and using the templates is recommended, to ensure
 you receive the latest updates, including updates to the sitespeed.io versions.
