+# 1. Make sure all the requirements in install_requires are defined correctly and that their version is the correct one
+# 2. Add all the non .py files to the package_data and to the MANIFEST.in file
+# 3. Make sure that all the python directories have an __init__.py file

 # 1. Create a new virtual environment using `virtualenv coach_env -p python3`
 # 2. Run `pip install -e .`
