Side note

I'm using this along with Marked2 Custom Preprocessor option and pandoc for rendering my Obsidian notes for the output, be it PDF, ODT, DOCX, RTF or HTML. Marked2 is very powerfull in that regard, allowing me to have References rendered from Zotero via autoupdated .bib file. I use that capabilities mostly for bigger Outlines, essays or papers where such case is a must.

full Args are (change your paths of course, and pick up style of your liking)

--citeproc -f markdown -M lang=pl-PL -t html5 --csl=/your/path/to/chicago.csl --bibliography=/your/path/to/Library.bib

With those in place sth like below is possible. The note is in Polish so sorry for that but you can see references - in Chicago style - rendered at the bottom

This is fantastic. Thank you for sharing!
