+### Change permalinks for one directory
 
 Let's say you have a directory of content templates like `recipes/cookies.md` and `recipes/soup.md` and 50 more. Each of these content templates has a title in their frontmatter. While you could manually set a permalink in the frontmatter of each recipe you can also dynamically generate the permalink inside a [Directory Data File](/docs/data-template-dir/) like `recipes.11tydata.js`.
 
 Because of the order of the [data cascade](/docs/data-cascade/) the title of a content template is not immediately available in the directory data file. However, `permalink` is a special case of implied [Computed Data](docs/data-computed/) and will have this data available. Inside of your directory data file `recipes.11tydata.js` you could write this:
 
-```javascript
-module.exports = {
-	permalink: function ({ title }) {
-		return `/recipes/${this.slugify(title)}`;
-	},
-};
-```
+{% include "snippets/permalinks/advanced.njk" %}
 
 The title will be [slugified](/docs/filters/slugify/) to be URL-friendly.
