Add README to databases
Context
This issue targets the databases we provide. Unfortunately we do not provide an overview of the databases in a README style.
Summary
It would be nice/helpful to have a schema of the database available for reference when browsing a database folder.
Additionally we could also provide pieces on how the dataset was created or limitations.
Steps to reproduce
