<!-- Set link to theme-settings, template-variables, theme functions -->

First, add the `xaringan-themer.css` file to the YAML header of your xaringan slides.

```yaml
output:
  xaringan::moon_reader:
    lib_dir: libs
    css: xaringan-themer.css
```

Then, in a hidden chunk just after the knitr setup chunk, load **xaringanthemer** and try one of the [theme functions][theme-functions].

````markdown
```{r xaringan-themer, include = FALSE}`r ""`
library(xaringanthemer)
style_mono_light(
  base_color = "#1c5253",
  header_font_google = google_font("Josefin Sans"),
  text_font_google   = google_font("Montserrat", "300", "300i"),
  code_font_google   = google_font("Droid Mono")
)
```
````
