 In other words, your Hugo site resides in the `site` directory, and you have a simple Dockerfile:
 
- FROM fundor333/hugo
+```dockerfile
+FROM fundor333/hugo
+```
 
 ## Building your site
 
 Based on this structure, you can easily build an image for your site:
 
- docker build -t my/image .
+```sh
+docker build -t my/image .
+```
 
 Your site is automatically generated during this build.
 
@@ -49,15 +55,21 @@ There are two options for using the image you generated:
 
 Using your image as a stand-alone image is the easiest:
 
- docker run -p 1313:1313 my/image
+```sh
+docker run -p 1313:1313 my/image
+```
 
 This will automatically start `hugo server`, and your blog is now available on <http://localhost:1313>.
 
 If you are using `boot2docker`, you need to adjust the base URL:
 
- docker run -p 1313:1313 -e HUGO_BASE_URL=http://YOUR_DOCKER_IP:1313 my/image
+```sh
+docker run -p 1313:1313 -e HUGO_BASE_URL=http://YOUR_DOCKER_IP:1313 my/image
+```
 
 The image is also suitable for use as a volume image for a web server, such as [nginx](https://registry.hub.docker.com/_/nginx/)
 
- docker run -d -v /usr/share/nginx/html --name site-data my/image
- docker run -d --volumes-from site-data --name site-server -p 80:80 nginx
+```sh
+docker run -d -v /usr/share/nginx/html --name site-data my/image
