        //Add a comment to the paragraph
        Comment comment = paragraph.appendComment("This is a comment");
        //Specify the author of the comment
        comment.getFormat().setAuthor("Shaun");
        //Specify the initial of the author

        replyComment1.getFormat().setAuthor("Chris");
        replyComment1.getBody().addParagraph().appendText("Hi, thank you for this information!");
        //Add the new comment as a reply to the first comment
        comment1.replyToComment(replyComment1);
