+# Fig Language - A Modern Scripting Language
+
+[简体中文](README_ZH-CN.md "Chinese version")
+
+**Fig** is a statically-typed, expression-oriented programming language designed for clarity, safety, and modern development practices. With features inspired by Go, Rust, and JavaScript, Fig aims to provide a productive development experience while maintaining strong type safety.
+
+## Features
+
+### 🚀 Core Language Features
+- **Static typing with type inference** - Strong typing with minimal annotations
+- **Modern control flow** - Full `for` loop support with proper scoping
+- **First-class functions** - Lambda expressions and closures
+- **Rich data structures** - Structs, lists, maps, and tuples
+- **Memory safety** - No null pointer exceptions, automatic memory management
+
+### 🔧 Technical Highlights
+- **Three-level scoping for loops** - Proper variable isolation in iterations
+- **Smart semicolon handling** - Flexible statement termination with RAII guards
+- **Comprehensive error handling** - Detailed error messages with source locations
+- **Clean C++ implementation** - Modern C++23 with RAII and smart pointers

+## Language Philosophy
+    Fig is designed around several core principles:
+
+    Clarity over cleverness - Code should be readable first
+
+    Safety by default - Prevent common errors at compile time
+
+    Modern ergonomics - Developer experience matters
+
+    Gradual learning - Simple to start, powerful when needed

+# Fig 语言 - 现代脚本语言
+
+[English](README.md "英文版本")
+
+**Fig** 是一种静态类型、面向表达式的编程语言，专为清晰性、安全性和现代开发实践而设计。Fig 融合了 Go、Rust 和 JavaScript 的灵感，旨在提供高效的开发体验，同时保持强大的类型安全。
+
+## 特性
+
+### 🚀 核心语言特性
+- **静态类型与类型推断** - 强类型系统，最少类型注解
+- **现代控制流** - 完整的 `for` 循环支持，正确的作用域管理
+- **一等公民函数** - Lambda 表达式和闭包
+- **丰富的数据结构** - 结构体、列表、映射和元组
+- **内存安全** - 无空指针异常，自动内存管理
+
+### 🔧 技术亮点
+- **三级循环作用域** - 迭代中正确的变量隔离
+- **智能分号处理** - 使用 RAII 守卫的灵活语句终止
+- **全面的错误处理** - 带有源码位置的详细错误信息

+## 语言设计哲学
+Fig 围绕几个核心原则设计：
+
+1. **清晰优于巧妙** - 代码首先应该可读
+2. **默认为安全** - 在编译时防止常见错误
+3. **现代人机工程学** - 开发者体验很重要
+4. **渐进式学习** - 入门简单，需要时功能强大
