## What it is
A graph-intensive, question-driven tutorial and reference collection for preparing for system design interviews, covering topics like caching, message queues, databases, distributed systems, and microservices. It includes translated Chinese articles and curated references, hosted as a GitBook.

## Use cases
- prepare for a system design interview
- learn how to design a URL shortener or chat system
- understand caching, sharding, and message queue concepts
- study distributed system fundamentals like CAP theorem
- find illustrated explanations of system architecture tradeoffs
- review common interview scenarios like designing YouTube or Uber

## When to choose
- you are preparing for backend or system design interviews
- you prefer visual, diagram-heavy explanations
- you want a free, curated reference covering both basics and in-depth topics

## When to avoid
- you need production-ready code or runnable implementations
- you need a formally maintained course with a license or guaranteed updates
- you are looking for frontend or mobile interview prep
