 While `pip` is bundled in this framework, it is **not recommended** to install any external libraries into your frameworks folder outside of what comes with the package. If you need to use or test external libraries not present in the package, it is recommended to use a [virtual environment](https://docs.python.org/3/library/venv.html) or a tool like [pyenv](https://github.com/pyenv/pyenv).

+Pull requests can and are encouraged to be issued to the `recommended` packages requirements file.

 # Updating packages
 This should be done in a clean virtual environment. After every Python package install, you can run `pip freeze | xargs pip uninstall -y` to cleanup the environment.
