 Working on updating my site and converting what I had worked on for an XML RSS feed into a more current JSON feed within a Kirby CMS controller file.

+## JSON Feed
 Since you're here you should browse the available elements in the  [jsonfeed.org](https://www.jsonfeed.org/version/1.1/) made by Manton Reese and Brent Simmons. Maybe there are a few elements you could add to this that I haven't. It looks much more flexible than the XML feed format. 
 
+Remember, we are now serving `application/feed+json` and the JSON feed format is `'version' => 'https://jsonfeed.org/version/1.1'`, also, the URL for the feed link in your header should use this PHP code:
+```PHP
+<link rel="alternate" type="application/feed+json" title="<?= $site->title()->esc() ?>" h
+  ref="<?= $site->rssfeed()->toPage()->url() ?>"  />
+```
+Of course, if you'd just like to link to your feed page directly, bypassing my silly panel page chooser for the feed, your header should use this more normal PHP code:
+```PHP
+<link rel="alternate" type="application/feed+json" title="<?= $site->title()->esc() ?>"
+  href="<?= page('feed')->url() ?>"  />
+```

 6. Next the controller file. This grabs the sections we want to include, sorts them, and grabs post images that use the typical Kirby `cover` image method but falls back to the first image available in each post.
 7. Then the controller creates the $items array for the feed. This is an array of all of your site pages that will be included.
 8. Then it takes the `cover` image and wraps it in a `figure`, adds `alt` text, a `figcaption` that allows links using the `->kirbytext()` powers, etc.

 10. Then it adds the `cover` to the beginning of that new `$content_html`.
 11. You can add in other field data you may have for your pages, here I have added `$materials` at the end, for a project I'm doing that I'll soon launch on the site.

 14. Then it assembles the `$items` using the various objects we've created as well as fields from each page.
 15. Returns the `$items` for use.
 16. You'll see all of the data come together in the template.
