adding a comment tag

On my site, melindamusil.com, the theme does not currently include a “click here to comment” type button at the bottom of each post. If readers click on the post title, they are taken to the single post/comment page, but I’d like to make the comment box a bit more obvious.

I’ve been looking through the wordpress docs to find the tag that would repair this issue but I have not yet been able to find it, so I’m also throwing it out here on this forum. What tag do I use to create a comment button below each post?
