  2. Set up CI

    This project includes GitHub Actions configuration files in .github/workflows. GitHub runs CI automatically for every push and pull request. No setup is required.

  3. Learn the design

    When you are ready to start coding, we recommend that you get some sense of the overall design by reading about AddressBook’s architecture.
