WMDE's repository with Docker images for Wikibase and related services is quite useful for spinning up local instances of those tools for experimentation, development, and building upon them.

However, the documentation is a bit sparse and hard to follow for a beginner, which hinders its usage, especially in events such as the Wikibase install party that happened during the 2019 hackathon.

At least the main entry-point documentation (i.e. the primary README file) should be improved so that newcomers can easily understand it and get started with the project.
