HTML inside md page won't get rendered by default in hugo 0.60+ (not relevant for Debian Buster yet)
Problem:
The default markdown renderer in hugo changed in 0.60 and by default doesn't render html tags in a markdown pages anymore. This breaks the main page for example.
Solution:
Either set the markdown renderer to blackfriday or set the "unsafe" flag for markdown.
Not sure if this change is already compatible with the current hugo version in Debian Buster, but it will be relevant with the next Debian upgrade.
