Difficulty with "Read More" summary at the end of a new post

Hey folks-

Got the site up and running but I’m having an issue with my posts. Essentially, when I make a post, I only want the first paragraph to present on the front page and the rest to be on the actual post when the reader clicks to it. I’ve been using the [read more] command under the post, which is doing the job of limiting the size of the post on the front page, but it is not providing a link at the end of the paragraph for the reader to click.

Below is my site, and my most recent post is an example. How do I get a little link at the bottom that says “Read more”?
