Switching from 'master' to 'main' in gitlab repositories under 2 minutes

https://twitter.com/Una/status/1271180494944829441 is about not using the word master to refer to the default branch in git repositories due to the reference to master/slave terminology.This video shows how to achieve that on gitlab in under 2 minutes. Of course if you have documentation that makes explicit reference to "master" branch, you will have to fix those too. Similarly for download links and so on. Perhaps someone will develop a firefox add-on that will automatically rename such links.
