When using the "Add to description" feature on the comment, make sure the comment is formatted properly so that it is clear that the text added was a comment (e.g. format it as a quote). Mention the author of the comment, as well as the date and time of writing it.

Optional: since every comment has a unique link and can become a thread - include a short link (e.g. hidden in a text/button) to quickly go to that comment (in the same tab).
