Pandoc Numbering Sections
When exporting from markdown to HTML you may want to switch from using H1s to H2s for the content since HTML should not include more than a single H1. To achieve this you can pass the option --shift-headaing-level-by=1 to Pandoc. This will shift all headings down by one level, making H2s into H3s, H3s into H4s, and so on.
