+# TVMC is a python package which is installed as a part of TVM Python packages. Accessing this

+# Alternatively, if you have TVM as a Python module on your ``$PYTHONPATH``, you can access this

+# Obtain a Tiny Model
+############################################################
+#
+# For this tutorial, we will use Magic Wand model from tflite micro. Magin Wand is a
+# Depthwise Convolution Layer model which recognizes gestures with an accelerometer.
+#
+# For this tutorial we will be using the model in tflite format.
+#
+# .. code-block:: bash
+#
+#     wget https://github.com/tensorflow/tflite-micro/raw/main/tensorflow/lite/micro/examples/magic_wand/magic_wand.tflite
+#
+
+############################################################
+# Compiling a TFLite model to a Model Library Format
+############################################################
+#
+# Model Library Format (MLF) is an output format that TVM provides for micro targets. MLF is a tarball
+# containing a file for each piece of the TVM compiler output which can be used on micro targets outside
+# TVM environment. Read more about `Model Library Format <https://tvm.apache.org/docs//arch/model_library_format.html>`_.
+#
+# Here, we generate a MLF file for `qemu_x86` Zephyr board. To generate MLF output for the `magic_wand` tflite model:
+#
+# .. code-block:: bash
+#
+#     tvmc compile magic_wand.tflite \
+#       --target='c -keys=cpu -link-params=0 -model=host' \
+#       --runtime=crt \
+#       --runtime-crt-system-lib 1 \
+#       --executor='graph' \
+#       --executor-graph-link-params 0 \
+#       --output model.tar \
+#       --output-format mlf \
+#       --pass-config tir.disable_vectorize=1 \
+#       --disabled-pass=AlterOpLayout
+#
+# This will generate a `model.tar` file which contains TVM compiler output files. To run this command for
+# a different Zephyr device, you need to update `target`. For instance, for `nrf5340dk_nrf5340_cpuapp` board
+# the target is ``--target='c -keys=cpu -link-params=0 -model=nrf5340dk'``.
+#
+
+
+############################################################
+# Create a Zephyr Projecg Using Model Library Format
+############################################################
+#
+# To generate a Zephyr project we use TVM Micro subcommand ``create``. We pass the MLF format and the path
+# for the project to ``create`` subcommand along with project options. Project options for each
+# platform (Zephyr/Arduino) are defined in their Project API server file. To generate Zephyr project, run:
+#
+# .. code-block:: bash
+#
+#     tvmc micro create \
+#       project \
+#       model.tar \
+#       zephyr \
+#       --project-option project_type=host_driven zephyr_board=qemu_x86
+#
+# This will generate a Zephyr project for `qemu_x86` zephyr board. To get more information about
+# TVMC Micro ``create`` subcommand:
+#
+# .. code-block:: bash
+#
+#     tvmc micro create --help
+#
+
+############################################################
+# Build and Flash Zephyr Project Using TVMC Micro
+############################################################
+#
+# Next step is to build the Zephyr project which includes TVM generated code for running the tiny model, Zephyr
+# template code to run a model in host_driven mode and TVM runtime source/header files. To build the project:
+#
+# .. code-block:: bash
+#
+#     tvmc micro build \
+#       project \
+#       zephyr \
+#       --project-option zephyr_board=qemu_x86
+#
+# This will build the project in `project` directory and generates binary files under `project/build`. To build
+# Zephyr project for a different Zephyr baord, change `zephyr_board` project option.
+#
+# Next, we flash the Zephyr binary file to Zephyr device. For `qemu_x86` Zephyr board this step does not
+# actually perform any action, however you need this step for physical hardware.

Review comment:
       I would add  "... actually perform any action **because QEMU will be used**, however..." just be super clear that `flash()` does nothing for that specific board.

+Executing a Tiny Model with TVMC Micro
+=========================
+**Author**: `Mehrdad Hessar <https://github.com/mehrdadh>`_
+
+This tutorial explains how to compile a tiny model for a micro device, 
+build a program on Zephyr platform to execute this model, flash the program 
+and run the model all using `tvmc micro` command.

+# .. note::
+#     This tutorial is explaining using TVMC Mirco on Zephyr platform. You need
+#     to install Zephyr dependencies before processing with this tutorial. Alternatively,
+#     you can run this tutorial in one of the following ways which has Zephyr depencencies already installed.
+#
+#     * Use `microTVM Reference Virtual Machines <https://tvm.apache.org/docs/how_to/work_with_microtvm/micro_reference_vm.html#sphx-glr-how-to-work-with-microtvm-micro-reference-vm-py>`_.
+#     * Use QEMU docker image provided by TVM. Following these you will download and login to the docker image:
+#     .. code-block:: bash
+#
+#         cd tvm
+#         ./docker/bash.sh tlcpack/ci-qemu

+# Using TVMC Micro
+############################################################
+#
+# TVMC is a python package which is installed as a part of TVM Python packages. Accessing this
+# package varies based on your machine setup. First option is to use ``tvmc`` command directly. ◊◊◊
+# Alternatively, if you have TVM as a Python module on your ``$PYTHONPATH``, you can access this
+# driver with ``python -m tvm.driver.tvm`` command. This tutorial will use TVMC command as
+# ``tvmc`` for simplicity.
+#
+# To check if you have TVMC command installed on your machine, you can run:
+#
+# .. code-block:: bash
+#
+#     tvmc --help
+#
+# To compile a model for microtvm we use ``tvmc compile`` subcommand. The output of this command
+# is used in next steps with ``tvmc micro`` subcommands. You can check the availability of TVMC Micro using:
+#
+# .. code-block:: bash
+#
+#     tvmc micro --help
+#
+# The main tasks that you can perform using ``tvmc micro`` are ``create``, ``build`` and ``flash``.
+# To read about specific options under a givern subcommand, use
+# ``tvmc micro <subcommand> --help``. We will use each subcommand in this tutorial.

+# Obtain a Tiny Model
+############################################################
+#
+# For this tutorial, we will use Magic Wand model from tflite micro. Magin Wand is a
+# Depthwise Convolution Layer model which recognizes gestures with an accelerometer.
+#
+# For this tutorial we will be using the model in tflite format.
+#
+# .. code-block:: bash
+#
+#     wget https://github.com/tensorflow/tflite-micro/raw/main/tensorflow/lite/micro/examples/magic_wand/magic_wand.tflite
+#
+
+############################################################
+# Compiling a TFLite model to a Model Library Format
+############################################################
+#
+# Model Library Format (MLF) is an output format that TVM provides for micro targets. MLF is a tarball
+# containing a file for each piece of the TVM compiler output which can be used on micro targets outside
+# TVM environment. Read more about `Model Library Format <https://tvm.apache.org/docs//arch/model_library_format.html>`_.
+#
+# Here, we generate a MLF file for `qemu_x86` Zephyr board. To generate MLF output for the `magic_wand` tflite model:
+#
+# .. code-block:: bash
+#
+#     tvmc compile magic_wand.tflite \
+#       --target='c -keys=cpu -link-params=0 -model=host' \
+#       --runtime=crt \
+#       --runtime-crt-system-lib 1 \
+#       --executor='graph' \
+#       --executor-graph-link-params 0 \
+#       --output model.tar \
+#       --output-format mlf \
+#       --pass-config tir.disable_vectorize=1 \
+#       --disabled-pass=AlterOpLayout
+#
+# This will generate a `model.tar` file which contains TVM compiler output files. To run this command for
+# a different Zephyr device, you need to update `target`. For instance, for `nrf5340dk_nrf5340_cpuapp` board
+# the target is ``--target='c -keys=cpu -link-params=0 -model=nrf5340dk'``.
+#
+
+
+############################################################
+# Create a Zephyr Projecg Using Model Library Format
+############################################################
+#
+# To generate a Zephyr project we use TVM Micro subcommand ``create``. We pass the MLF format and the path
+# for the project to ``create`` subcommand along with project options. Project options for each
+# platform (Zephyr/Arduino) are defined in their Project API server file. To generate Zephyr project, run:
+#
+# .. code-block:: bash
+#
+#     tvmc micro create \
+#       project \
+#       model.tar \
+#       zephyr \
+#       --project-option project_type=host_driven zephyr_board=qemu_x86
+#
+# This will generate a Zephyr project for `qemu_x86` zephyr board. To get more information about
+# TVMC Micro ``create`` subcommand:
+#
+# .. code-block:: bash
+#
+#     tvmc micro create --help
+#
+
+############################################################
+# Build and Flash Zephyr Project Using TVMC Micro
+############################################################
+#
+# Next step is to build the Zephyr project which includes TVM generated code for running the tiny model, Zephyr
+# template code to run a model in host_driven mode and TVM runtime source/header files. To build the project:
+#
+# .. code-block:: bash
+#
+#     tvmc micro build \
+#       project \
+#       zephyr \
+#       --project-option zephyr_board=qemu_x86
+#
+# This will build the project in `project` directory and generates binary files under `project/build`. To build
+# Zephyr project for a different Zephyr baord, change `zephyr_board` project option.
