+# Quick Start
+
+## Installation
+
+```bash
+# Install from PyPI
+pip install leanup
+
+# Or clone the repository and install
+git clone https://github.com/Lean-zh/LeanUp.git
+cd LeanUp
+pip install -e .
+```
+
+## Basic Usage
+
+### Initialize elan
+
+```bash
+# View help
+leanup --help
+
+# Install elan
+leanup init
+
+# View current status
+leanup status
+```
+
+### Install Lean Toolchain
+
+```bash
+# Install latest stable Lean toolchain
+leanup install
+
+# Install specific Lean toolchain version
+leanup install v4.14.0
+```
+
+### Manage Toolchains
+
+```bash
+# Proxy execute elan commands
+leanup elan --help
+leanup elan toolchain list
+leanup elan toolchain install stable
+leanup elan default stable
+```
+
+### Repository Management
+
+```bash
+# Install Mathlib
+leanup repo install leanprover-community/mathlib4
+
+# Install specific branch or tag
+leanup repo install leanprover-community/mathlib4 -b v4.14.0
+
+# Install to custom directory
+leanup repo install Lean-zh/leanup -d /path/to/custom/dir
+
+# Control build options
+leanup repo install leanprover-community/mathlib4 --lake-build
+
+# Interactive mode
+leanup repo install leanprover-community/mathlib4 -i
+
+# Specify packages to build
+leanup repo install Lean-zh/repl --build-packages "REPL,REPL.Main"
+
+# List installed repositories
+leanup repo list
+
+# Search repositories in specified directory
+leanup repo list --search-dir /path/to/repos
+
+# Filter repositories by name
+leanup repo list -n mathlib
+```
+
+## Using InstallConfig
+
+The `InstallConfig` class provides a programmatic way to configure repository installations:
+
+```python
+from pathlib import Path
+from leanup.repo.manager import InstallConfig
+
+# Create installation configuration
+config = InstallConfig(
+    suffix="leanprover-community/mathlib4",
+    source="https://github.com",
+    branch="main",
+    dest_dir=Path("/path/to/repos"),
+    dest_name="mathlib4_main",
+    lake_update=True,
+    lake_build=True,
+    build_packages=["REPL", "REPL.Main"],
+    override=False
+)
+
+# Check if configuration is valid
+if config.is_valid:
+    print(f"Will install to: {config.dest_path}")
+    
+# Execute installation
+config.install()
+
+# Update configuration
+new_config = config.update(branch="v4.3.0", override=True)
+```
+
+## Using the RepoManager
+
+The `RepoManager` class provides functionality for managing directories and git repositories:
+
+```python
+from leanup.repo.manager import RepoManager
+
+# Create a repo manager
+repo = RepoManager("/path/to/your/directory")
+
+# Check if it's a git repository
+if repo.is_gitrepo:
+    print("This is a git repository")
+    status = repo.git_status()
+    print(f"Current branch: {status['branch']}")
+    print(f"Is dirty: {status['is_dirty']}")
+
+# Clone a repository
+success = repo.clone_from(
+    "https://github.com/owner/repo.git", 
+    branch="main", 
+    depth=1
+)
+
+# File operations
+repo.write_file("test.txt", "Hello world")
+content = repo.read_file("test.txt")
+repo.edit_file("test.txt", "world", "universe", use_regex=False)
+
+# List files and directories
+files = repo.list_files("*.lean")
+dirs = repo.list_dirs()
+
+# Execute commands
+stdout, stderr, returncode = repo.execute_command(["ls", "-la"])
+```
+
+## Using LeanRepo for Lean Projects
+
+```python
+from leanup.repo.manager import LeanRepo
+
+# Create a Lean repo manager
+lean_repo = LeanRepo("/path/to/lean/project")
+
+# Get project information
+info = lean_repo.get_project_info()
+print(f"Lean version: {info['lean_version']}")
+print(f"Has lakefile.toml: {info['has_lakefile_toml']}")
+print(f"Has lakefile.lean: {info['has_lakefile_lean']}")
+print(f"Has lake-manifest.json: {info['has_lake_manifest']}")
+print(f"Build directory exists: {info['build_dir_exists']}")
+
+# Lake operations
+lean_repo.lake_init("my_project", "std", "lean")
+lean_repo.lake_update()
+lean_repo.lake_build("MyTarget")
+lean_repo.lake_env_lean("Main.lean", json=True)
+lean_repo.lake_clean()
+lean_repo.lake_test()
+
+# Install using configuration
+config = InstallConfig(
+    suffix="leanprover-community/mathlib4",
+    lake_update=True,
+    lake_build=False
+)
+lean_repo.install(config)
+```

+# 快速开始
+
+## 安装
+
+```bash
+# 从 PyPI 安装
+pip install leanup
+
+# 或者克隆仓库后安装
+git clone https://github.com/Lean-zh/LeanUp.git
+cd LeanUp
+pip install -e .
+```
+
+## 基础使用
+
+### 初始化 elan
+
+```bash
+# 查看帮助
+leanup --help
+
+# 安装 elan
+leanup init
+
+# 查看当前状态
+leanup status
+```
+
+### 安装 Lean 工具链
+
+```bash
+# 安装最新稳定版 Lean 工具链
+leanup install
+
+# 安装特定版本的 Lean 工具链
+leanup install v4.14.0
+```
+
+### 管理工具链
+
+```bash
+# 代理执行 elan 命令
+leanup elan --help
+leanup elan toolchain list
+leanup elan toolchain install stable
+leanup elan default stable
+```
+
+### 仓库管理
+
+```bash
+# 安装 Mathlib
+leanup repo install leanprover-community/mathlib4
+
+# 安装特定分支或标签
+leanup repo install leanprover-community/mathlib4 -b v4.14.0
+
+# 安装到自定义目录
+leanup repo install Lean-zh/leanup -d /path/to/custom/dir
+
+# 控制构建选项
+leanup repo install leanprover-community/mathlib4 --lake-build
+
+# 交互式

+leanup repo list
+
+# 在指定目录中搜索仓库
+leanup repo list --search-dir /path/to/repos
+
+# 按名称过滤仓库
+leanup repo list -n mathlib
+```
+
+## 使用 InstallConfig
+
+`InstallConfig` 类提供了编程方式配置仓库安装：
+
+```python
+from pathlib import Path
+from leanup.repo.manager import InstallConfig
+
+# 创建安装配置
+config = InstallConfig(
+    suffix="leanprover-community/mathlib4",
+    source="https://github.com",
+    branch="main",
+    dest_dir=Path("/path/to/repos"),
+    dest_name="mathlib4_main",
+    lake_update=True,
+    lake_build=True,
+    build_packages=["REPL", "REPL.Main"],
+    override=False
+)
+
+# 检查配置是否有效
+if config.is_valid:
+    print(f"将安装到: {config.dest_path}")
+    
+# 执行安装
+config.install()
+
+# 更新配置
+new_config = config.update(branch="v4.3.0", override=True)
+```
+
+## 使用 RepoManager
+
+`RepoManager` 类提供了管理目录和 git 仓库的功能：
+
+```python
+from leanup.repo.manager import RepoManager
+
+# 创建仓库管理器
+repo = RepoManager("/path/to/your/directory")
+
+# 检查是否为 git 仓库
+if repo.is_gitrepo:
+    print("这是一个 git 仓库")
+    status = repo.git_status()
+    print(f"当前分支: {status['branch']}")
+    print(f"是否有修改: {status['is_dirty']}")
+
+# 克隆仓库
+success = repo.clone_from(
+    "https://github.com/owner/repo.git", 
+    branch="main", 
+    depth=1
+)
+
+# 文件操作
+repo.write_file("test.txt", "Hello world")
+content = repo.read_file("test.txt")
+repo.edit_file("test.txt", "world", "universe", use_regex=False)
+
+# 列出文件和目录
+files = repo.list_files("*.lean")
+dirs = repo.list_dirs()
+
+# 执行命令
+stdout, stderr, returncode = repo.execute_command(["ls", "-la"])
+```
+
+## 使用 LeanRepo 管理 Lean 项目
+
+```python
+from leanup.repo.manager import LeanRepo
+
+# 创建 Lean 仓库管理器
+lean_repo = LeanRepo("/path/to/lean/project")
+
+# 获取项目信息
+info = lean_repo.get_project_info()
+print(f"Lean 版本: {info['lean_version']}")
+print(f"有 lakefile.toml: {info['has_lakefile_toml']}")
+print(f"有 lakefile.lean: {info['has_lakefile_lean']}")
+print(f"有 lake-manifest.json: {info['has_lake_manifest']}")
+print(f"构建目录存在: {info['build_dir_exists']}")
+
+# Lake 操作
+lean_repo.lake_init("my_project", "std", "lean")
+lean_repo.lake_update()
+lean_repo.lake_build("MyTarget")
+lean_repo.lake_env_lean("Main.lean", json=True)
+lean_repo.lake_clean()
+lean_repo.lake_test()
+
+# 使用配置安装
+config = InstallConfig(
+    suffix="leanprover-community/mathlib4",
+    lake_update=True,
+    lake_build=False
+)
+lean_repo.install(config)
