title: Markdown formula display in GitHub
body: <p>When I write an R markdown file in RStudio and <code>Knit HTML</code>, my formulas (inline using $..$ or display using $$..$$) can be displayed properly. However, when I push my .md file to GitHub, these formulas cannot be displayed. They only show $..$ and $$..$$. Is there a way to let GitHub know how to parse latex formulas? Thanks!</p>
