A README.md file is a very useful component of any project repository. As you can (or may soon) see, it is automatically rendered on GitHub as a simple "homepage" for your project. Instructions for creating your own GitHub repository from these files may be given during the course. The same instructions are also summarized in CONTRIBUTING.md.
If the repository does not contain a data folder, download a zipped data file to accompany the worksheets. A "good" data-synthesis pipeline stores the data separate from the code—we may take a shortcut for these lessons.
