 ### Content Structure
 
-The tutorial content is located in the `content/` directory. Each route contains a number prefix (`1.`) to indicate the order and will be removed in the final URL. For each route, we use a folder with an `index.md` to serve the extra files. A `.template` folder can be placed with the `index.md` file to provide the template for the playground.
