12-26: Well-organized Table of Contents.The TOC is comprehensive and properly linked, making navigation effortless for users. Good structural foundation for the documentation.
53-64: Architecture section properly highlights DTO usage.Lines 61-62 correctly emphasize that Services handle Entity-DTO mapping, reinforcing the best practice of not exposing domain entities directly to clients. This aligns well with the codebase's design principles.
81-133: Clear Getting Started instructions with proper subsection organization.The local development (lines 83-108) and Docker deployment (lines 109-133) sections provide step-by-step guidance with appropriate port references (9000, 9001). The separation between detached and foreground modes for Docker is helpful.
167-193: Testing section covers coverage targets and naming conventions.The section appropriately distinguishes between unit testing approaches (lines 183-186) and coverage targets (lines 188-192), providing developers with clear expectations for test implementation and coverage metrics.
1-218: Comprehensive, production-ready documentation restructuring.The modernized README effectively transforms the project documentation from minimal to comprehensive. Key strengths:
- ✅ Clear architecture and layer responsibility descriptions (aligns with retrieved learnings about BookDTO usage)
- ✅ Explicit JDK 21 requirement with compatibility warnings
- ✅ Step-by-step local development and Docker deployment paths
- ✅ Well-formatted API Reference table with realistic JSON schema
- ✅ Proper cross-linking and section organization
All PR objectives are thoroughly addressed. The only actionable items are verifying cross-file references and adding platform-agnostic guidance for the coverage report viewer.

Verify referenced files exist in the repository.
The README references external files that must be present for the documentation to be complete:
.github/copilot-instructions.md(line 199)CONTRIBUTING.md(line 203)assets/images/structure.svg(line 55)assets/images/swagger.png(line 165)
Run the following script to verify these files are present in the repository:
Also verify that docker-compose.yml exists to support the Docker Deployment instructions (lines 109-127).

docker-compose.yml is missing and required to support documented Docker Deployment instructions.
The README's Docker Deployment section (lines 109–127) provides commands like docker compose up that expect a docker-compose.yml file to exist in the repository root. Without it, users following the documentation will encounter failures. The file must be created to make the Docker Deployment instructions functional.
All other referenced files (.github/copilot-instructions.md, CONTRIBUTING.md, assets/images/structure.svg, assets/images/swagger.png) are present and valid.

In README.md around line 199, the Docker Deployment instructions reference
running docker compose up but the repository lacks a docker-compose.yml; add a
docker-compose.yml at the repository root that defines the services, networks,
volumes and environment variables required by the README commands (e.g., app
service built from the project, any database or reverse-proxy services, ports,
and compose v2 syntax), ensure it matches the commands and paths in the README
(including any build context, ports, and env file names), and commit the new
file so the documented docker compose commands succeed.

@nanotaboada, you're absolutely right, and I apologize for the oversight!
The compose.yaml file does exist in the repository, and it's the modern, recommended naming convention for Docker Compose files. Both compose.yaml and docker-compose.yml are valid, but Docker's documentation now favors compose.yaml.
I've verified the file, and it correctly defines the service with ports 9000 and 9001 as documented in your README. The Docker Deployment instructions are fully supported. Thank you for the clarification and the helpful link!

Learning: This repository uses `compose.yaml` (not `docker-compose.yml`) for Docker Compose configuration, which is the modern naming convention supported by Docker Compose.
