## What it is
A tutorial series repository that walks through building Go software from scratch in 7 days each, including a Gin-like web framework (Gee), a groupcache-like distributed cache (GeeCache), a GORM/xorm-like ORM (GeeORM), and an RPC framework (GeeRPC). Each project is accompanied by step-by-day articles explaining the design and implementation.

## Use cases
- learn Go by building a web framework from scratch
- understand how distributed caches like groupcache work
- study how an ORM framework is implemented in Go
- learn trie-based routing and middleware design
- prepare for Go backend interviews
- find a hands-on Go starter project

## When to choose
- you want to deeply understand Go internals by reimplementing popular libraries
- you prefer tutorial-driven learning with incremental daily steps
- you are preparing for Go engineering interviews

## When to avoid
- you need production-ready frameworks or libraries for real applications
- you want actively maintained software with new features
- you need comprehensive documentation beyond the tutorial articles

- domain: tutorials, developer-tools, programming-languages, web-development, databases
- platform: go, cross-platform
