ABSTRACT
As mentioned in Chapter 1, this book is not a comprehensive guide to knitr or rmarkdown. In this chapter, we briefly explain some basic concepts and syntax in knitr and rmarkdown. If you have any further questions, youmay post them on StackOverflow (https://stackoverflow.com) and tag your questions with r, knitr, rmarkdown, and/or bookdown, whichever is appropriate.
