README excerpt
.. raw:: html The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with security in mind. The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained systems: from simple embedded environmental sensors and LED wearables to sophisticated smart watches and IoT wireless gateways. The Zephyr kernel supports multiple architectures, including ARM (Cortex-A, Cortex-R, Cortex-M), Intel x86, ARC, Tensilica Xtensa, and RISC-V, SPARC, MIPS, and a large number of `supported boards`_. .. below included in doc/introduction/introduction.rst Getting Started *************** Welcome to Zephyr!
