Quarto enables you to weave together content and executable code into a finished presentation. To learn more about Quarto presentations see https://quarto.org/docs/presentations/.
Slides should be rendered automatically to gh-pages, in this case: https://uomresearchit.github.io/Quarto-RevealJS-R/
The repo is R - specific only in that it installs R, rmarkdown and knitr as part of the render-quarto.yml build action.
