As answered by mjgpy3, you can include html - no tags needed, but it'll be sanitized before display and the only tags allowed are in this whitelist.

The list currently includes:

h1 h2 h3 h4 h5 h6 h7 h8 br b i strong em a pre code img tt div ins del sup sub p ol ul table thead tbody tfoot blockquote dl dt dd kbd q samp var hr ruby rt rp li tr td th s strike summary details caption figure figcaption abbr bdo cite dfn mark small span time wbr

but no iframe.
