As a first set of documentation pages for potential users of HeFQUIN (users != developers who want to work on HeFQUIN itself), we need the following pages.

• How to start the Web service via Docker, change the federation description that it uses, and how to issue queries to the service.
• How to start the Web service from the latest release package, change the federation description that it uses, and how to issue queries to the service.
• How to run queries using the CLI tool in the latest release package, including a detailed description of the arguments of the CLI tool.
• How to run queries using the latest source code version of the CLI tool or the Web service.
• How to specify the federation to be queried, including a documentation of the most important parts of the RDF vocabulary defined for this purpose.
• Additionally, we need to create a README.txt file that we put in the top-level directory of the release packages and that contains a short version of these points above, including pointers to the respective documentation pages.
• A similar summary of these points needs to be added to the README.md of the repo.
