+# CutThenThink 打包指南
+
+## 方式一：使用 build.sh 脚本（推荐）
+
+在您的本地环境（有管理员权限）中运行：
+
+```bash
+cd /path/to/CutThenThink
+bash build.sh
+```
+
+---
+
+## 方式二：手动打包
+
+### 1. 安装 PyInstaller
+
+```bash
+# 使用 pipx（推荐）
+pipx install pyinstaller
+
+# 或使用系统包管理器
+sudo apt install python3-pyinstaller
+```
+
+### 2. 安装项目依赖
+
+```bash
+pip install -r requirements.txt
+```
+
+### 3. 执行打包
+
+```bash
+python3 -m PyInstaller \
+    --name "CutThenThink" \
+    --windowed \
+    --onefile \
+    --add-data "src:src" \
+    --hidden-import=PyQt6.QtCore \
+    --hidden-import=PyQt6.QtGui \
+    --hidden-import=PyQt6.QtWidgets \
+    --hidden-import=sqlalchemy \
+    src/main.py
+```
+
+### 4. 测试运行
+
+```bash
+./dist/CutThenThink
+```
+
+---
+
+## 打包参数说明
+
+| 参数 | 说明 |
+|------|------|
+| `--name` | 应用名称 |
+| `--windowed` | 无控制台窗口 |
+| `--onefile` | 单文件打包 |
+| `--add-data` | 添加数据文件（源代码） |
+| `--hidden-import` | 隐式导入模块 |
+
+---
+
+## 打包后
+
+可执行文件位置：`dist/CutThenThink`
+
+分发时建议：
+1. 将 `dist/CutThenThink` 打包为 tar.gz
+2. 创建安装脚本
+3. 包含 README 说明
