For this, there are directories called "blog" or "includes" where you can create text files and link to them, just like in my example.

https://elpis.ws

You don't need to automate this; you can use HTML for layout.

The side menu doesn't use the navigation tool; the links there were manually formatted. You can use the blog in the same way. Or, if you need individual pages (a page within a page), they can be placed in includes and displayed like this

<a href="/cgi-bin/cms/nameofthepage">nameof thepage</a><br>

Look closely at what the code looks like; it's hardcoded without using any HamsterCMS tools.
