Get Started!

Ready to contribute? Here's how to set up the project for local development.

  1. Fork the copier repo on GitHub.
  2. Clone your fork locally:
git clone
  1. Install your local copy into a virtualenv.
python -m virtualenv .venv
source .venv/bin/activate
make install
  1. Create a branch for local development:
git checkout -b name-of-your-bugfix-or-feature

Now you can make your changes locally.

  1. When you're done making changes, check that your changes pass all tests
pytest -x .
flake8 .

To have multiple Python versions on the same machine for running tox, I recommend using pyenv (do not confuse it with pipenv,).

  1. Commit your changes and push your branch to GitHub:
git add .
git commit -m "Detailed description of your changes."
git push origin name-of-your-bugfix-or-feature
  1. Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request has code, it should include tests.
  2. Run tox and make sure that the tests pass for all supported Python versions.


To run a subset of tests:

$  pytest tests/
