Stahel was right [-@StaWW91]. You can find all supportedcitation formats [here](http://pandoc.org/MANUAL.html#citations).It is a collection of multiple templates on the basisof LaTeX, which are tailored so that I can work happily under the umbrella of`bookdown`. `bookdownplus` helps you write academic journal articles, guitarbooks, chemical equations, mails, calendars, and diaries.
