    From the README

    This repository contains the OpenTelemetry Astronomy Shop, a microservice-based distributed system intended to illustrate the implementation of OpenTelemetry in a near real-world environment.

    We've already made huge progress, and development is ongoing. We hope to represent the full feature set of OpenTelemetry across its languages in the future.

    If you'd like to help (which we would love), check out our contributing guidance.
