+# Notes for TensorFlow.js-Converter Developers
+
+## Python Development
+
+There are some Python libraries, binary and tests in the `python/` directory.
+
+It is recommended to do your Python development and testing in a
+[virtualenv](https://virtualenv.pypa.io/en/stable/) or
+[pipenv](https://docs.pipenv.org/).
+
+As a prerequisite, install the following dependencies for python testing
+```sh
+cd python
+pip install -r requirements.txt
+```
+
+For Python linter, install `pylint`, e.g.,
+* `apt-get install -y pylint`
+
+To run the Python linter:
+```sh
+cd python
+pylint tensorflowjs
+```
+
+To run the python unit tests, there are two options. You can choose the one that
+you prefer.
+
+1. Run the tests using the `run-python-tests.sh` script:
+
+   ```sh
+   cd python
+   ./run-python-tests.sh
+   ```
+
+2. Run the tests using Bazel. See bazel installation guide
+   [here](https://docs.bazel.build/versions/master/install.html). Once bazel
+   is installed, do:
+
+   ```sh
+   cd python
+   bazel test tensorflowjs/...
+   ```
+
+Be sure to run the tests under **both** Python 2 and Python 3.
+
+### Building and testing the tensorflowjs pip package
+
+```sh
+cd python
+
+# You need to specify a folder where the pip wheel file will be stored, e.g.,
+./build-pip-package.sh /tmp/my_tensorflowjs_pip
+
+# If the script succeeds, you can use `pip install` to install the pip package:
+
+pip install --force-reinstall \
+  /tmp/my_tensorflowjs_pip/tensorflowjs-0.0.1-py2-none-any.whl
+```
+
+`build-pip-package.sh` provides a flag (`--test`) with which you can run a
+test-on-install after building the pip package. Make sure you are using a
+`virutalenv` or `pipenv` to avoid changing your base environmnet.
+
+```sh
+./build-pip-package.sh --test /tmp/my_tensorflowjs_pip
+```
