 # Linux Networking
 
+Infix aims to support all Linux Networking constructs.  The YANG models
+used to describe the system are chosen to fit well and leverage the
+underlying Linux kernel's capabilities.  The `ietf-interfaces.yang`
+model forms the base, extended with `ietf-ip.yang` and other layer-3
+IETF models.  The layer-2 bridge and aggregate models are defined by
+Infix to exploit the unique features not available in IEEE models.
