Preparation and Repository

See The-Compiler/pytest-basics on GitHub for exercise code and preparation steps. Please make sure you have at least a virtualenv with pytest (or the full requirements.txt in the repo) set up and the code cloned before the training starts, so that we don't lose any time with the boring setup parts.

See the README for detailed setup instructions.
