 ## Install dependencies
+
 - If you have downloaded/forked this repository you can install the R dependencies with (assuming your working directory is at the top level of the repo):
+
   ```r
   # install.packages("devtools") # uncomment if devtools not installed
   devtools::install_dev_deps()
   ```
+
 - You can install the Stata dependencies, in Stata, with
-  ``` stata
+
+  ```stata
   do depdendency
   ```

 ## Building the book
 
 - If you need to install LaTeX, in R install the tinytex package (which is included in the dependencies) and run
-  ``` r
+
+  ```r
   tinytex::install_tinytex()
   ```
 
 - Render all formats
+
   ```r
   rmarkdown::render_site(encoding = 'UTF-8')
   ```
 
 - Render the PDF book
-  ``` r
+
+  ```r
   rmarkdown::render_site(output_format = 'bookdown::pdf_book', encoding = 'UTF-8')
   ```
 
 - Render the HTML book
-  ``` r
+
+  ```r
   rmarkdown::render_site(output_format = 'bookdown::gitbook_book', encoding = 'UTF-8')
   ```
 
 - Render the EPUB book
+
   ```r
   rmarkdown::render_site(output_format = 'bookdown::epub_book', encoding = 'UTF-8')
   ```
 
 - Preview a specific chapter
-  ``` r
+
+  ```r
   bookdown::preview_chapter("chapter-filename.Rmd")
   ```
 
 - To build the chapters containing Stata code:
+
   - You need Stata installed on your machine.
   - You need to install Doug Hemken's [**Statamarkdown**](https://github.com/Hemken/Statamarkdown) package, which is now on CRAN and is installed when you run `devtools::install_dev_deps()`, or install with
-    ``` r
+
+    ```r
     install.packages("Statamarkdown")
     ```
+
   - If your version of Stata is installed at a default installation location the **Statamarkdown** package will find it. If your version of Stata is installed at a bespoke file path you'll need to set the file path to with something like
-    ``` r
+
+    ```r
     library(Statamarkdown)
     stataexe <- "C:/Program Files/Stata17/StataSE-64.exe"
     knitr::opts_chunk$set(engine.path = list(stata = stataexe))
     ```
+
   - Install the Stata dependencies, in Stata, with:
-    ``` stata
+
+    ```stata
     do dependency
     ```
