 *Inspired by <https://github.com/rstudio/renv/blob/master/TODO.md>*
 
 - [x] Implement site builder for a collection of notebooks leveraging the [rmarkdown site generator](https://bookdown.org/yihui/rmarkdown/rmarkdown-site.html), [render_site](https://rdrr.io/cran/rmarkdown/man/render_site.html)
+- [x] Update `DESCRIPTION` and use description data in `README.Rmd`
 - [ ] Add problems and solutions to the training log, including how to get around the limitation that you can't debug R Notebooks. (considered and rejected the knitr-spin.R approach)
 - [ ] Add notes on resolving the error message generated by `use_package("tidyverse")`
 - [ ] Write a utility/maintenance function to verify: `renv::status`, `renv::clean`, and possibly `renv::update` - see <https://github.com/rstudio/renv/blob/master/R/status.R>

+- [ ] Refactor site builder as an R function
+  - wrapper for `rmarkdown::render_site()`
+  - run the build in a temporary directory like `render_site()`
+  - re-use code from `render_site()` to create list of R Notebooks
+  - dynamically build the `_site.yml` file using [yaml](https://github.com/viking/r-yaml/) with configuration settings passed to the wrapper function
+  - dynamically build the `index.Rmd` using `DESCRIPTION`
+  - support for additional links in the navbar
+  - order links by Title, not filename
+  - better logic for converting `html_notebook` to `html_document`
 - [ ] Implement [pkgdown](https://pkgdown.r-lib.org) ?
