Supporting information
- Jira Ticket: SE-4149
Testing instructions
- Check the sandbox and verify everything is working as expected.
- Check the pipeline and make sure the markdown quality check passes.
- If you want to go the extra mile, do the following:
- Test adding two header 1s to the same file - that shouldn't be possible.
- Test adding a header 1 and a header 3 consecutively, without the header 2.
- Run
make quality-markdown
and you should get two violations.
