A super simple RSS template for anything
Each time you want a new item add the following code. Just make sure to replace the title, date, link, and description with the relevant info.
<item>
<title>Example Post 1</title>
<pubDate>Tue, 26 Jan 2021 19:00:00 -0400</pubDate>
<link>https://example.com/post2</link>
<description>An example post</description>
</item>
Go to line 7, add a new break in the code, and then paste the new item code on line 7 to add a new item to the list (new ones always go above old items).
