 This repository contains a dummy R project which allows us to

+build a website for Extendr using `pkgdown`.
 
 To build the site locally:
 
-```
-      remotes::install_github("r-lib/pkgdown")
-      devtools::install()
-      pkgdown::build_site()
+```r
+remotes::install_github("r-lib/pkgdown")
+devtools::install()
+pkgdown::build_site()
 ```
 
 There is a github action that builds the site and deploys to
 the `gh-pages` branch when pushing to `main`.
 
 On linux, you will also need:
 
-```
+```shell
 sudo apt install fontconfig libfreetype2-dev libfontconfig1-dev libharfbuzz-dev libfribidi-dev pandoc

 ## Installation - R
 
-There are two ways you can use the extendr API from R. First, you can use the [rextendr](https://extendr.github.io/rextendr/) package to call individual Rust functions from an R session. Second, you can write an R package that uses compiled Rust code, see the [helloextendr](https://github.com/extendr/helloextendr) repo for a minimal example.
