Setting up Arkham Comments

Warning: I’m a n00b. Some of your speak may not make sense to me.

Here’s a link to the GitHub repository.

The documentation gives the following code example:

<div class="comment-section">
    {{> commentsBox id=documentId}}
</div>

I’m having trouble setting up a database/collection where the comments can live. I don’t know what to put in place of documentId. I have done the following:

I have manually inserted data into the “comments” collection Arkham created upon install. When I do this, I’m able to reply to the comment that was created but no text is displayed.

I have also added both the insecure and autopublish packages with no luck.
