This repository holds templates for creating workshops to be hosted using Educates. For detailed instructions on how to create workshops using these templates see the Educates documentation.

Note that if creating a repository using GitHub's repository template feature, you need to wait until the GitHub action triggered upon repository creation has been run before creating a checkout of the repository. This is because the GitHub action will rewrite the initial repository content with customized workshop content.
