mmm, tried to answer from a phone, so not a lengthy as you may have wanted...
Sorry to say, but your interpretation of the docs page is wrong... https://www.tinyportal.net/docs/index.php
This page is the TP 'frontpage' and this is configured to only hold blocks on that site...
So there are NO articles shown on the frontpage, just a series of blocks that link to articles..
On our docs site the articles are linked to from the frontpage.
Articles are grouped in categories.
Example category is the category 'Articles'
Each category has a page itself, showing articles in that category. In the category settings you define the layout and the panels showing on that category page.
The category page is: https://www.tinyportal.net/docs/index.php?cat=92
Here you see all articles in that category. the first one (WHAT ARE ARTICLES?) is showing in full, the others just as a link.
If you click on the article title you get to the article page itself.
This is the article page: https://www.tinyportal.net/docs/index.php?page=What-are-articles
Both the category and article page have two panels showing: the left panel (obviously) and the bottom panel (showing the Back to top link)
Panels themselves are explained here: https://www.tinyportal.net/docs/index.php?cat=94
