| # Introduction |
| |
| The Zephyr OS is a small-footprint kernel designed for use on |
| resource-constrained and embedded systems: from simple embedded |
| environmental sensors and LED wearables to sophisticated embedded |
| controllers, smart watches, and IoT wireless applications. |
| |
| See the [zephyrproject.org](https://zephyrproject.org) site for more |
| information about the project and becoming a member, and this [summary |
| of Zephyr resources](https://docs.zephyrproject.org/latest/introduction/index.html#resources) |
| to help you find your way around the project. |
| |
| ## Supported Boards |
| |
| The Zephyr kernel supports multiple architectures, including ARM |
| Cortex-M, Intel x86, ARC, NIOS II, Tensilica Xtensa, and RISC-V 32. For |
| details, see the [latest supported boards |
| documentation](https://docs.zephyrproject.org/latest/boards/index.html). |
