 ## Contribute text to the chapters
 
-Contribute directly to chapters (01-Intro.Rmd). Either through the GitHub website and direct edits to the R markdown files prefixed with chapter numbers (eg. 01-intro.Rmd). You can write both markdown or R, and even python code. The site is built using the R package [bookdown](https://bookdown.org/) through GitHub Actions, so all you need to do is edit the R markdown file and GitHub will take care of the rest.
