+## 🚀 快速参考
+
+### 完整构建流程
+
+```bash
+# 1. 生成绑定和图标
+wails3 task common:generate:bindings
+wails3 task common:generate:icons
+
+# 2. 构建前端
+cd frontend
+npm install
+npm run build
+cd ..
+
+# 3. 构建应用（各平台）
+cd build/windows  && wails3 task build PRODUCTION=true  # Windows
+cd build/linux    && wails3 task build PRODUCTION=true  # Linux
+cd build/darwin   && wails3 task build PRODUCTION=true  # macOS
+
+# 4. 打包应用（各平台）
+cd build/windows  && wails3 task package  # NSIS 安装程序
+cd build/linux    && wails3 task package  # AppImage + deb + rpm + archlinux
+cd build/darwin   && wails3 task package  # .app bundle
+```
+
+---
+
+## 📝 注意事项
+
+1. **变量传递：** Task 命令支持通过 `VAR=value` 格式传递变量
+2. **路径问题：** 相对路径基于 Taskfile.yml 所在目录
+3. **依赖顺序：** 某些任务有依赖关系（通过 `deps:` 定义）
+4. **环境变量：** 使用 `env:` 定义的环境变量会自动设置

+# 字体压缩工具使用指南
+
+## 📖 简介
+
+`font_compressor.py` 是一个通用的字体压缩工具，可以：
+- ✅ 将 TTF、OTF、WOFF 字体文件转换为 WOFF2 格式
+- ✅ 支持相对路径和绝对路径
+- ✅ 自动生成 CSS 字体定义文件
+- ✅ 智能识别字体字重和样式
+- ✅ 批量处理整个目录（包括子目录）
+
+## 🚀 前置要求
+
+安装 Python 依赖包：
+
+```bash
+pip install fonttools brotli
+```
+
+## 📝 使用方法
+
+### 基础用法
+
+```bash
+# 进入 fonts 目录
+cd frontend/src/assets/fonts
+
+# 交互式模式处理当前目录
+python font_compressor.py
+
+# 处理相对路径的 Monocraft 目录
+python font_compressor.py Monocraft
+
+# 处理相对路径并指定压缩级别
+python font_compressor.py Monocraft -l basic
+```
+
+### 生成 CSS 文件
+
+```bash
+# 压缩 Monocraft 字体并生成 CSS 文件
+python font_compressor.py Monocraft -l basic -c ../styles/monocraft_fonts.css
+
+# 压缩 Hack 字体并生成 CSS
+python font_compressor.py Hack -l basic -c ../styles/hack_fonts_new.css
+
+# 压缩 OpenSans 字体并生成 CSS
+python font_compressor.py OpenSans -l medium -c ../styles/opensans_fonts.css
+```
+
+### 高级用法
+
+```bash
+# 使用绝对路径
+python font_compressor.py E:\Go_WorkSpace\voidraft\frontend\src\assets\fonts\Monocraft -l basic -c monocraft.css
+
+# 不同压缩级别
+python font_compressor.py Monocraft -l basic      # 基础压缩，保留所有功能
+python font_compressor.py Monocraft -l medium     # 中等压缩，平衡大小和功能
+python font_compressor.py Monocraft -l aggressive # 激进压缩，最小文件
+```
+
+## ⚙️ 命令行参数
+
+| 参数 | 说明 | 示例 |
+|------|------|------|
+| `directory` | 字体目录（相对/绝对路径） | `Monocraft` 或 `/path/to/fonts` |
+| `-l, --level` | 压缩级别 (basic/medium/aggressive) | `-l basic` |
+| `-c, --css` | CSS 输出文件路径 | `-c monocraft.css` |
+| `--version` | 显示版本信息 | `--version` |
+| `-h, --help` | 显示帮助信息 | `-h` |
+
+## 📊 压缩级别说明
+
+### basic（基础） - 推荐
+- 保留大部分字体功能
+- 适合网页使用
+- 压缩率约 30-40%
+
+### medium（中等）
+- 移除一些不常用的功能
+- 平衡文件大小和功能
+- 压缩率约 40-50%
+
+### aggressive（激进）
+- 最大程度减小文件大小
+- 可能影响高级排版功能
+- 压缩率约 50-60%
+
+## 📁 输出结果
+
+### 字体文件
+压缩后的 `.woff2` 文件会保存在原文件相同的目录下，例如：
+- `Monocraft/ttf/Monocraft-Bold.ttf` → `Monocraft/ttf/Monocraft-Bold.woff2`
+- `Hack/hack-regular.ttf` → `Hack/hack-regular.woff2`
+
+### CSS 文件
+生成的 CSS 文件会包含：
+- 自动识别的字体家族名称
+- 正确的字重和样式设置
+- 使用相对路径的字体引用
+- 按字重排序的 `@font-face` 定义
+
+生成的 CSS 示例：
+
+```css
+/* 自动生成的字体文件 */
+/* 由 font_compressor.py 生成 */
+
+/* Monocraft 字体家族 */
+
+/* Monocraft Light */
+@font-face {
+  font-family: 'Monocraft';
+  src: url('../fonts/Monocraft/ttf/Monocraft-Light.woff2') format('woff2');
+  font-weight: 300;
+  font-style: normal;
+  font-display: swap;
+}
+
+/* Monocraft Bold */
+@font-face {
+  font-family: 'Monocraft';
+  src: url('../fonts/Monocraft/ttf/Monocraft-Bold.woff2') format('woff2');
+  font-weight: 700;
+  font-style: normal;
+  font-display: swap;
+}
+```
+
+## 🎯 实际使用示例
+
+### 示例 1: 压缩 Monocraft 字体
+
+```bash
+cd frontend/src/assets/fonts
+python font_compressor.py Monocraft -l basic -c ../styles/monocraft_fonts.css
+```
+
+这将：
+1. 扫描 `Monocraft/ttf` 和 `Monocraft/otf` 目录
+2. 将所有字体文件转换为 WOFF2
+3. 在 `frontend/src/assets/styles/monocraft_fonts.css` 生成 CSS 文件
+
+### 示例 2: 批量处理多个字体目录
+
+```bash
+cd frontend/src/assets/fonts
+
+# 压缩 Monocraft
+python font_compressor.py Monocraft -l basic -c ../styles/monocraft_fonts.css
+
+# 压缩 OpenSans
+python font_compressor.py OpenSans -l basic -c ../styles/opensans_fonts.css
+
+# 压缩 Hack（已有 CSS，只需生成新版本对比）
+python font_compressor.py Hack -l basic -c ../styles/hack_fonts_new.css
+```
+
+## 🔍 字体信息自动识别
+
+工具会自动从文件名识别：
+- **字重**：Thin(100), Light(300), Regular(400), Medium(500), SemiBold(600), Bold(700), Black(900)
+- **样式**：normal, italic
+- **字体家族**：自动去除字重和样式后缀
+
+支持的命名格式：
+- `FontName-Bold.ttf`
+- `FontName_Bold.otf`
+- `FontName-BoldItalic.ttf`
+- `FontName_SemiBold_Italic.woff`
+
+
