+Infix is a free, Linux-based, immutable[^1] operating system based on
+[Buildroot][2] and completely modeled in YANG using [sysrepo][3].  This
+allows for full remote control and monitoring using NETCONF or RESTCONF.
+Initially focused on switches and routers, Infix has grown to be useful
+for many other use-cases as well.
+
+An immutable operating system greatly enhances security.  Configuration
+and data, e.g, containers, is stored on separate partitions to ensure
+complete separation from system files and allow for seamless backup,
+restore, and provisioning.
+
+### Core Values
 
 - Runs from a squashfs image on a read-only partition
 - Single configuration file on a separate partition
-- Linux switchdev provides open switch APIs
-- Atomic upgrades to secondary partition
-- Highly security focused
+- Linux switchdev (DSA) provides open switch APIs
+- Atomic upgrades using common A/B partitioning
+- Highly security focused — LTS kernel + Buildroot
+
+### YANG vs NETCONF vs RESTCONF
 
 The entire system is modeled using [YANG][1] with standard IETF models
 and dedicated models when needed to fully leverage Linux capabilities.
 Meaning, not only is the system configuration derived from YANG, but
 also system state and any operations (RPC/actions), like upgrade.

+The *wire protocol* to interact with Infix devices is NETCONF (xml over
+ssh) and RESTCONF (json over https).  The latter is particularly useful
+for scripting (and demo) purposes, while the former has more tooling
+available, e.g., [Clixon Controller][4], which is a NETCONF controller.

+In itself, Infix is perfectly suited for dedicated networking tasks and
 native support for Docker containers provides a versatile platform that
 can easily be adapted to any customer need.  Be it legacy applications,
 network protocols, process monitoring, or edge data analysis, it can run
 close to end equipment.  Either directly connected on dedicated Ethernet
 ports or indirectly using virtual network cables to exist on the same
 LAN as other connected equipment.
 
+### Summary
+
 The simple design of Infix provides complete control over both system
 and data, minimal cognitive burden, and makes it incredibly easy to get
 started.
