I am writing a document in markdown, and I read that I could change the font to Arial like this:
---
fontfamily: arev
---
But it did not work. But when I try to change the font to Times, it's working fine
---
fontfamily: times
---
So how do I change the font to Arial?
Pandoc uses LaTeX per default for PDF generation, so it depends on your TeX installation.
If you're on TeX Live you can use most in this font catalogue.
