 ## Special markers
 There are special markers for dungeons, which link to Watabou's one-page dungeon generator (https://watabou.itch.io/one-page-dungeon).  These special markers show a preview in the notes.  In the notes editor, click on the <> button to show the HTML code used for the preview.  You can use the same text to generate your own previews to images.  The text is below:
