-Introduction to the Zephyr Project
-##################################
-
-The Zephyr Kernel is 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.
-
-It is designed to be supported by multiple architectures, including
-ARM Cortex-M, Intel x86, and ARC. The full list of supported platforms
-can be found :ref:`here <board>`.
-
-Licensing
-*********
-
-The Zephyr project associated with the kernel makes it available
-to users and developers under the Apache License, version 2.0.
-
-Distinguishing Features
-***********************
-
-The Zephyr Kernel offers a number of features that distinguish it from other
-small-footprint OSes:
-
-#. **Single address-space OS**. Combines application-specific code
-   with a custom kernel to create a monolithic image that gets loaded
-   and executed on a system's hardware. Both the application code and
-   kernel code execute in a single shared address space.
-
-#. **Highly configurable**. Allows an application to incorporate *only*
-   the capabilities it needs as it needs them, and to specify their
-   quantity and size.
-
-#. **Resources defined at compile-time**. Requires all system resources
-   be defined at compilation time, which reduces code size and
-   increases performance.
-
-#. **Minimal error checking**. Provides minimal run-time error checking
-   to reduce code size and increase performance. An optional error-checking
-   infrastructure is provided to assist in debugging during application
-   development.
-
-#. **Extensive suite of services** Offers a number of familiar services
-   for development:
-
-   * *Multi-threading Services* for both priority-based, non-preemptive
-     fibers and priority-based, preemptive tasks with optional round robin
-     time-slicing.
-
-   * *Interrupt Services* for both compile-time and run-time registration
-     of interrupt handlers.
-
-   * *Inter-thread Synchronization Services* for binary semaphores,
-     counting semaphores, and mutex semaphores.
-
-   * *Inter-thread Data Passing Services* for basic message queues, enhanced
-     message queues, and byte streams.
-
-   * *Memory Allocation Services* for dynamic allocation and freeing of
-     fixed-size or variable-size memory blocks.
-
-   * *Power Management Services* such as tickless idle and an advanced idling
-     infrastructure.
