+============================
+**Author**: `Tom Gall <https://github.com/tom-gall>`_
+
+This tutorial is an introduction to working with MicroTVM and TFLite models with Relay.
+"""
+######################################################################
+# Setup
+# -----
+#
+# To get started, TFLite package needs to be installed as prerequisite.
+# 
+# install tflite
+# .. code-block:: bash
+#
+#   pip install tflite=2.1.0 --user
+#
+# or you could generate TFLite package yourself. The steps are the following:
+#
+#   Get the flatc compiler.
+#   Please refer to https://github.com/google/flatbuffers for details
+#   and make sure it is properly installed.
+#
+# .. code-block:: bash
+#
+#   flatc --version
+#
+# Get the TFLite schema.
+#
+# .. code-block:: bash
+#
+#   wget https://raw.githubusercontent.com/tensorflow/tensorflow/r1.13/tensorflow/lite/schema/schema.fbs
+#
+# Generate TFLite package.
+#
+# .. code-block:: bash
+#
+#   flatc --python schema.fbs
+#
+# Add current folder (which contains generated tflite module) to PYTHONPATH.
+#
+# .. code-block:: bash
+#
+#   export PYTHONPATH=${PYTHONPATH:+$PYTHONPATH:}$(pwd)
+#
+# To validate that the TFLite package was installed successfully, ``python -c "import tflite"``
+#
+# CMSIS needs to be downloaded and the CMSIS_ST_PATH environment variable setup
+# This tutorial only supports the STM32F7xx series of boards.
+# Download from : https://www.st.com/en/embedded-software/stm32cubef7.html
+# After you've expanded the zip file
+#
+# .. code-block:: bash
+#
+# export CMSIS_ST_PATH=/path/to/STM32Cube_FW_F7_V1.16.0/Drivers/CMSIS
