## Overview

This repository is a collection of Spring Boot and Spring Cloud tutorial samples, not one deployable application. A learner selects an example and observes its demonstrated behavior, from configuration and REST endpoints through persistence, messaging, background work, and service-to-service patterns. The graph preserves those distinct tutorial branches rather than joining them into a runtime pipeline. Internal links are limited to relationships visible in excerpts or the source index; README links identify documented capabilities, not implementation details.
