* Folder/project structure explanation
* Data flow between components
* External integrations (APIs, databases, services)
* Authentication/authorization approach (if applicable)
* Scalability and deployment considerations
* Future extensibility considerations (if relevant)

* Key features
* Tech stack overview
* Installation instructions
* Environment variables configuration (if applicable)
* How to run the project (development and production)
* Basic usage examples
* Project structure overview (high-level)
* Link to additional documentation (ARCHITECTURE.md, PRODUCT.md, CONTRIBUTING.md)

Guidelines:

* Keep it clear and developer-friendly.
* Optimize for first-time visitors to quickly understand the project.
* Use badges if appropriate (build status, license, version).
