Hi, I hope this is the right place to ask for a bit of help? (I’ve asked on discord as well). I’m trying to add a custom collection to my website. Have read the docs, but can’t seem to get it to work. I’ve added -

collections: 
    samples: 
        output: true

to bridgetown.config.yml, created ‘_samples’ folder in ‘/src’, with a test.md file in there which includes title: “xyz” front matter, then created an index page at ‘/src’ called ‘samples.md’, containing:

<ul>
  {% for post in collections.samples.resources %}
    <li>
      <a href="{{ post.relative_url }}">{{ post.data.title }}</a>
    </li>
  {% endfor %}
</ul>

(essentially the same for loop that’s in the posts.md file and works fine out-of-the-box). The page displays when I link to it, but my test “xyz” post doesn’t show up. What am I missing?
