 Hugo has the ability to create a skeleton site:
 
-    $ hugo new site /path/to/site
+{{< nohighlight >}}$ hugo new site <i>path/to/site</i>
+{{< /nohighlight >}}
 
 For the rest of the operations, we will be executing all commands from within the site directory.
 
-    $ cd /path/to/site
+{{< nohighlight >}}$ cd <i>path/to/site</i>
+{{< /nohighlight >}}
 
 The new site will have the following structure
 
-      ▸ archetypes/
+{{< nohighlight >}}  ▸ archetypes/
   ▸ content/
   ▸ data/
   ▸ layouts/
   ▸ static/
     config.toml
+{{< /nohighlight >}}
 
 Currently the site doesn’t have any content, nor is it configured.
