+Device classes
+--------------
+Gluon currently is aware of two device classes. Depending on the device class, different
+features can be installed onto the device.
+
+The ``tiny`` device-class contains devices with the following limitations:
+
+* All devices with less than 64 MB of system memory
+* All devices with less than 7 MB of usable firmware space
+* Devices using a single ath10k radio and less than 128MB of system memory
