What is this?
Zephyr is an open source real-time operating system (RTOS) — a small-footprint kernel for resource-constrained embedded devices, supporting many hardware architectures and built with security in mind.

It does not run on your desktop.

The Getting Started Guide covers installing and configuring the toolchain.
