+## Build a Wheel file locally
+**First time setup**
+```sh
+pip install --upgrade pip setuptools wheel packaging build
+mkdir -p ./dist
+```
+**Updating the wheel file**
+```sh
+rm -rf ./dist/*
+cd ./aws-opentelemetry-distro
+python3 -m build --outdir ../dist
+cd ../dist
+pkg_version=$(grep '__version__' ../aws-opentelemetry-distro/src/amazon/opentelemetry/distro/version.py | awk -F '"' '{print $2}')
+pip wheel --no-deps aws_opentelemetry_distro-${pkg_version}.tar.gz
+pip install aws_opentelemetry_distro-${pkg_version}-py3-none-any.whl --force-reinstall
+cd ..
+```
+
+## Test a sample App
+1. Setup env and install project dependencies
+```sh
+mkdir auto_instrumentation
+virtualenv auto_instrumentation
+source auto_instrumentation/bin/activate
+pip install flask requests boto3 opentelemetry-instrumentation-flask opentelemetry-instrumentation-botocore opentelemetry-instrumentation
+```
+2. Install the project pkg by following "Build a Wheel file locally" step above. Please make sure to install “aws-opentelemetry-distro” by following steps instead of install "opentelemetry-distro” directly.
+3. Add AWS test account credential into the terminal, setup environment variable and run sample server:
+```sh
+export OTEL_PYTHON_DISTRO="aws_distro"
+export OTEL_PYTHON_CONFIGURATOR="aws_configurator"
+opentelemetry-instrument python ./sample-applications/simple-client-server/server_automatic_s3client.py
+```
+4. Prepare a client.py, an example is `./tests/client.py`, open a new terminal and run sample client:
+```sh
+python ./sample-applications/simple-client-server/client.py testing
+```
+The span content will be output into terminal console
