 &lt;p&gt;I just needed to create a &lt;a href=&quot;https://jekyllrb.com/docs/collections/&quot;&gt;&lt;em&gt;collection&lt;/em&gt;&lt;/a&gt; to put my &lt;a href=&quot;/2016/Migrating-from-Drupal-to-Jekyll&quot;&gt;“live drafts”&lt;/a&gt; into it, but the deprecated &lt;em&gt;jekyll-paginate&lt;/em&gt; plugin provided with GitHub pages didn’t support collections.&lt;/p&gt;
