 ### Build the lesson locally
 
-To render the lesson locally, you will need to have [R][r] installed. Instructions for using R with the Carpentries template is [available](https://carpentries.github.io/workbench/#installation) but some additional setps have been taken to make sure the enivronment is reproducible using the [`{renv}`](https://rstudio.github.io/renv/articles/renv.html) package and an `renv.lockfile` is included which allows the environment to be re-created along with dependencies.

-After cloning the repository, you can set up the `renv` and install all packages with:
 ``` r
-renv::restore()
+renv::init()
 # Optionally update packages
 renv::update()
 ```
 Once you have installed the dependencies, you can render the pages locally by starting R in the project root and running:
+
 ``` r
 sandpaper::serve()
 ```
+
+When building the site subsequently, you may need to run `renv::activate()` first.
+
 This will build the pages and start a local web-server in R and open it in your browser. These pages are "live" and will respond to local file changes if you save them.
