 This is the firmware for the Arduino-based hardware that is part of the AYAB project.
 
+## Branching Model
+
+**Development of the latest and upcoming features happens on the 'main' branch.** For each major release, a dedicated maintenance branch is created to manage bug fixes, security patches, and backporting for that specific release. These branches follow the naming convention <version>-maint (e.g. *0.95-maint*). This approach allows us to continue forward development while ensuring stability and long-term support for previous versions.
