 # Workshop setup
 
-To complete this workshop you will need to create a repository with a copy of the contents of this repository. While this can be done by [forking a repository](https://docs.github.com/en/get-started/quickstart/fork-a-repo), the goal of a fork is to eventually merge code back into the original (or upstream) source. In our case we want a separate copy as we don't intend to merge our changes. This is accomplished through the use of a [template repository](https://docs.github.com/en/repositories/creating-and-managing-repositories/creating-a-template-repository). Template repositories are a great way to provide starters for your organization, ensuring consistency across projects.
