Reference docs allow to adjust the style of #docx and #odt files. Generate a reference doc with

pandoc -o refdoc.docx --print-default-data-file reference.docx

Open the refdoc.docx document and modify the styles in there to your liking. Then pass the modified document to let pandoc use the new styles:

pandoc --reference-doc=refdoc.docx ...

#pandoc #referenceDoc
