Clone the repository. Step through the execution with a debugger to watch how control flows from the client code through the pattern interfaces.

The bridges the gap between incompatible interfaces, which is highly useful when integrating third-party SaaS platforms or legacy SOAP services into a modern gRPC or RESTful pipeline.
