## Details

tocr uses the following two [HTML comments](https://www.w3schools.com/TAGS/tag_comment.asp) to mark the beginning and end of an auto-generated TOC:

``` html
<!-- TOC BEGIN -- leave this comment untouched to allow auto update -->
```

``` html
<!-- TOC END -- leave this comment untouched to allow auto update -->
```

`tocr::add_toc()` supports the comment format of [other similar software](#see-also) like [doctoc](https://github.com/thlorenz/doctoc). If you stumble upon
software-generated Markdown TOCs which aren't recognized by `tocr::add_toc()`, feel free to [file an issue](http://gitlab.com/rpkg.dev/tocr/issues) or even add
support for it on your own and submit a [merge request](https://gitlab.com/rpkg.dev/tocr/merge_requests).

```{r}
#| label: pkg-doc
#| eval: !expr '!isTRUE(getOption("pal.build_readme.is_pkgdown"))'
#| results: asis
#| echo: false

pkgsnip::md_snip(id = "pkgdown_site") %>%
  paste0("## Documentation\n\n",
         "[![Netlify Status](https://api.netlify.com/api/v1/badges/0bb75d33-429c-4295-8de9-94a11ebc27d2/deploy-status)]",
         "(https://app.netlify.com/sites/tocr-rpkg-dev/deploys)\n\n",
         .) %>%
  pal::cat_lines()
```
