+### Getting, printing, and regenerating the QR code (from your portal)
+
+You can produce the QR code yourself for any facility you're assigned to:
+
+- **One facility** — open the facility from your dashboard/facilities list and
+  click **QR Code**. This opens a printable page with the code and its link;
+  click **Print** to print it.
+- **All your facilities at once** — on the **Facilities** page click **Print All
+  QR Codes** for a single sheet covering every facility you're assigned to.
+- **Regenerate** — on a facility's QR page, click **Regenerate** to issue a new
+  code. Use this if a posted code is defaced or you want to retire an old one.
+  **Any previously printed code for that facility stops working**, so reprint and
+  repost after regenerating.
