## What it is
rCore-Tutorial-v3 is a set of educational OS kernel labs that teach how to build a Unix-like operating system from scratch in Rust (with C variants) targeting RISC-V 64 and x86-32. It includes a ~4K line kernel with processes, threads, virtual memory, a file system, and a shell, plus a detailed Chinese-language tutorial book.

## Use cases
- learn how to write an operating system kernel from scratch
- study OS concepts like virtual memory, scheduling, and file systems hands-on
- learn systems programming in Rust
- build a Unix-like OS for RISC-V in a university OS course
- run a teaching kernel on QEMU or K210 dev boards
- understand how syscalls, processes, and concurrency work at the kernel level

## When to choose
- you are a beginner wanting to learn OS development without prior assembly or architecture knowledge
- you want a small, readable (~4K LoC) kernel codebase to study and extend
- you prefer Rust for systems programming education
- you need structured lab exercises with a companion tutorial book

## When to avoid
- you need a production-grade OS kernel
- you require English documentation (the tutorial is currently Chinese-only)
- you want to develop for ARM or other non-RISC-V/x86 platforms
- you need a maintained project with frequent updates

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: interpreter, programming-language, developer-tools
- domain: operating-systems, education, tutorials
- platform: windows, rust, cpp
- tags: operating-system, kernel, risc-v, rust-os, qemu, teaching-os, rcore, x86, systems-programming, linux, macos
