## Overview

System Design Academy is a curated learning-resource catalog, not an application runtime. Readers browse the README’s topic collections and follow links to case studies, fundamentals, interview material, AI engineering resources, or white papers. The available tree contains only README.md and LICENSE.md; relationships below are limited to navigation and linked content explicitly shown in the README excerpt.

Main entry points: [`README.md`](https://github.com/systemdesign42/system-design-academy/blob/main/README.md) (Catalog index)
