## Overview

This is a Django REST and React notes application, presented in the README as part of a broader DevOps exercise. The user-facing workflow is to browse notes, open or create one, then save, update, or delete it through the API. Backend views route these operations through serializers and the Note model. The README documents MySQL and container, Kubernetes, and dual CI/CD deployment capabilities, but their implementation files are absent from the supplied tree, so those infrastructure branches cannot be mapped here. Edges reflect excerpts or README statements.
