How do I install/update Themezer-3DS?

In FBI, open Remote Install, choose Scan QR Code, and scan the QR code under Install with FBI on the Themezer homepage. Or install themezer-3ds.cia from the latest release with FBI.

Themezer-3DS keeps itself up to date from then on. Already using Anemone3DS? It can still scan Themezer’s QR codes.
