+#' Recipes for Building Container Images
+#'
+#' A list containing several useful recipes for container building. Useful for the `post_installation_steps` argument of [dockerize()]. Available recipes are:
+#' * `texlive`: install pandoc and LaTeX, useful for rendering RMarkdown
+#' * `texlivefull`: Similar to the above, but install the full distribution of TeX Live (~ 3GB)
+#' * `quarto`: install quarto and tinytex
+#' * `clean`: clean up the container image by removing cache
+#' * `make`: install GNU make
