OpenHarmony is a distributed OS that is designed to run on top of variety of OS kernels. Currently the supported kernels are Zephyr, Yocto, and FreeRTOS. To build OpenHarmony image, you need add multiple layers called meta-ohos. meta-ohos is an umbrella meta layer containing all layers required to build OpenHarmony Image basing on existing kernel meta-layers. This section describes how to build, add layers, and run the OpenHarmony image.
