How To Set an Expanded Blog Post as the Homepage

You know the page you see when you click on the title of a blog posting? It has the comment (reply) form already showing at the bottom.

HOW do I get that page to load on my site’s homepage?

When users arrive at my site, I want them to be able to read the full article. And then when they get to the bottom of the article, I want them to see the discussion thread and also the form to add their comments.

I’ve searched all over and can’t find any documentation on this.

Thanks in advance. please help…
