   .. tab-item:: Update Your Operating System

        * Ensure your host system is up to date. We can use following commands to update os.

        .. code-block:: c

                $ sudo apt-get update
                $ sudo apt-get upgrade

   .. tab-item:: Install Requirements and Dependencies

        * Note that both Ninja and Make are installed with these instructions; you only need one.

        .. code-block:: c

                $ sudo apt-get install --no-install-recommends git cmake ninja-build gperf \
                ccache dfu-util device-tree-compiler wget \
                python3-dev python3-pip python3-setuptools python3-tk python3-wheel xz-utils file \
                make gcc gcc-multilib g++-multilib libsdl2-dev libmagic1

   .. tab-item:: Dependencies

        * A recent CMake version is required.

        * Check what version you have by using below command.
          
        .. code-block:: c

                $ cmake --version.

        * The current minimum required version for the main dependencies are:

        .. code-block:: c

                CMake                   3.20.5
                Python                  3.8
                Devicetree compiler     1.4.6

        * Verify the versions of the main dependencies installed on your system by entering:

        .. code-block:: c

                $ cmake --version
                $ python3 --version
                $ dtc --version
