+Supported Images
+################
+
+To create a custom Linux distribution to match the product requirements, 
+All Scenarios OS includes a set of predefined images for developing a product image.
+
+Linux Kernel
+************
+
+The Linux kernel is a free and open-source Unix-like operating system (OS) 
+kernel that serves as the primary interface between the computer's hardware and its processes.
+
+All Scenarios OS supports the following images listed in the table:
+
+.. list-table:: Linux supported images
+   :header-rows: 1
+
+   * - Image Name
+     - Description
+   * - allscenarios-image-base
+     - 
+	   * All Scenarios OS image including the base OS software stack.
+	   * This image also includes middleware and application packages to support a wide range of hardware which includes WiFi, Bluetooth, sound, and serial ports. 
+   * - allscenarios-image-extra
+     - 
+	   * All Scenarios OS Wayland image including the base OS software stack. This is a Wayland protocol and Weston reference compositor-based image.
+	   * It uses the Wayland protocol and implementation to exchange data with its clients.
+	   * This image provides the Wayland protocol libraries and the reference Weston compositor and includes a Wayland-capable terminal program.
+
+To build a Linux-based image for a supported machine, see :ref:`Linux Kernel Build Flavour <Linux_Kernel>`.
+
+Zephyr Kernel
+*************
+
+The Zephyr OS is a well-known security-oriented real-time operating system (RTOS) 
+that is intended for use on resource-constrained and embedded systems. 
+
+For more detailed information on Zephyr OS Kernel, see `Zephyr documentation <https://docs.zephyrproject.org/latest/index.html#>`_.
+
+All Scenarios OS supports the following images for the Zephyr OS kernel:
+
+.. list-table:: Zephyr supported images
+   :header-rows: 1
+
+   * - Image Name
+     - Description
+   * - zephyr-philosophers
+     - A sample Zephyr application implementing the Dining Philosophers problem.
+
+To build a Zephyr-based image for a supported machine, see :ref:`Zephyr Kernel Build Flavour <Zephyr_Kernel>`.
+
+FreeRTOS Kernel
+***************
+
+The FreeRTOS kernel is a real-time operating system (RTOS) that runs on a variety 
+of platforms which is used to build microcontroller-based embedded applications. 
+
+The standard RTOS kernel binary image ranges from 4000 to 9000 bytes. 
+All Scenarios OS supports the following images for FreeRTOS Kernel:
+
+.. list-table:: FreeRTOS supported images
+   :header-rows: 1
+
+   * - Image Name
+     - Description
+   * - freertos-demo
+     - Machine configuration for running an ARMv5 system on QEMU.
+
+To build a FreeRTOS-based image for a supported machine, see :ref:`FreeRTOS Kernel Build Flavour <FreeRTOS_Kernel>`.
