 ### Using Docker

 In case you do not want to install Nodejs to your system, you can also use Docker
 
 First build the Docker image which will contain N Nodejs - thats all this documentation has no dependencies
-```
+
+```sh
 docker build . -t naemon/docs
 ```
 
 Now run the Docker container and navigate to `http://127.0.0.1:5173` in your browser.
 The container watches for file changes and will automatically regenerate the website if needed.
