Whoops, didn't see your post.
- Configure your world / Settings / Basic: add "Worlds Without Number" to your world under "ROLE PLAYING GAMING SYSTEM"
- Then go to Advanced Tools / Statblocks in the left side menu.
- There you now see a dropdown box on the left that should contain the "Worlds Without Number Character Sheet", select it and click "create a new stat block"
When you are done, you can either use the blockid at the bottom of the sheet to include it into an article, or for your "character" articles, in the footer section, you can directly select a sheet, it's then being displayed below the article.
