+# Byox (Build Your Own X)
+
 ## Definition
-Byox（Build Your Own X）是一种学习编程的方法论，通过从零重建技术来深入理解其工作原理。核心理念是"What I cannot create, I do not understand"。
 
-## Covered Topics
-该方法覆盖22个技术领域：
-- 3D Renderer（3D渲染器）
-- Augmented Reality（增强现实）
-- BitTorrent Client（BitTorrent客户端）
-- Blockchain / Cryptocurrency（区块链/加密货币）
-- Bot（机器人）
-- Command-Line Tool（命令行工具）
-- Database（数据库）
-- Docker（容器）
-- Emulator / Virtual Machine（虚拟机）
-- Front-end Framework（前端框架）
-- Game（游戏）
-- Git（版本控制）
-- Network Stack（网络协议栈）
-- Neural Network（神经网络）
-- Operating System（操作系统）
-- Physics Engine（物理引擎）
-- Programming Language（编程语言）
-- Regex Engine（正则引擎）
-- Search Engine（搜索引擎）
-- Shell（终端）
-- Template Engine（模板引擎）
-- Text Editor（文本编辑器）
-- Visual Recognition System（视觉识别系统）
-- Voxel Engine（体素引擎）
-- Web Browser（浏览器）
-- Web Server（Web服务器）
+**Byox** (Build Your Own X) is a learning methodology that advocates for mastering programming and technology understanding by **rebuilding complex systems from scratch**. The guiding principle comes from physicist Richard Feynman:
 
-## Learning Approach
-- 多语言实现：同一技术可用多种语言实现（C++、Python、JavaScript、Go、Rust等）
-- 手把手教程：step-by-step 形式的学习资源
-- 原理优先：不使用现成库，从底层原理实现
+> *"What I cannot create, I do not understand."*
 
-## Related Concepts
-- [[Vibe Coding]] — 与 Byox 对比，Vibe Coding 是 AI 代写，Byox 是自己手写
-- [[深度工作]] — Byox 需要深度专注，符合深度工作的理念
+## Core Philosophy
+
+Instead of passively consuming knowledge about how a technology works, practitioners:
+
+1. **Choose a technology** they want to understand deeply
+2. **Study existing implementations** and documentation
+3. **Rebuild it from scratch** using a chosen programming language
+4. **Gain deep insight** into how it works internally
+
+## Coverage
+
+The Byox methodology covers **26 technology domains**:
+
+- **Systems**: Operating System, Docker, Container
+- **Languages**: Programming Language, Compiler, Interpreter, Regex Engine
+- **Data**: Database, NoSQL, Key-Value Store
+- **Web**: Web Browser, Web Server, Search Engine
+- **Tools**: Git, Shell, Command-Line Tool, Text Editor, Template Engine
+- **Graphics**: 3D Renderer, Voxel Engine, Physics Engine
+- **AI/ML**: Neural Network, Visual Recognition
+- **Networks**: Network Stack, BitTorrent Client
+- **Entertainment**: Game, Emulator/Virtual Machine
+- **Other**: Blockchain/Cryptocurrency, Augmented Reality, Bot

+## Why Byox Works
+
+1. **Active Learning**: Building forces deep engagement
+2. **Hidden Complexity**: Reveals implementation details textbooks skip
+3. **Transferable Skills**: Generalizes to understanding other systems
+4. **Portfolio Building**: Creates tangible proof of understanding
+5. **Confidence**: Only truly knowing something if you can create it
