The Delinquent now includes supplemental content, so that it's a fully-fleshed-out playbook including all of the content that the core books have. The new documents include the following information:

• Design Notes
• Playing the Delinquent
• Notes on Moves and Extras
• Suggested Moves From Other Playbooks
• Inspirations for the Delinquent
• GMing for the Delinquent
• Instructions for Playing With The Joined

I really recommend you give it a read!
