title: RMarkdown: How to change headline in table of contents in R Markdown?
body: <p>When I'm using the <code>toc: yes</code> command, the document contains "Content" as the headline of the table of contents. Due to the fact that I want to write this document in german, I also want to change the headline of the table of contents to the equivalent german word. Any suggestions on how to change this?</p>
