This repository provides detailed, chapter-by-chapter notes summarizing the concepts covered in both volumes of the System Design Interview books by Alex Xu. It breaks down complex architectural topics into digestible markdown files for easy reading and review. The content covers essential concepts like rate limiting, consistent hashing, and scaling from zero to millions of users. It also includes specific case studies detailing the architecture of major platforms such as YouTube, Google Drive, and distributed message queues. The structured format allows readers to quickly grasp core system design principles without reading the entire source material.

These notes are ideal for software engineers preparing for system design interviews at major tech companies. They are also highly valuable for junior developers looking to understand how large-scale distributed systems are architected.

• Chapter summaries: Offers distinct markdown files dedicated to individual chapters from the original books.
