+### 使用数据模型自动渲染
+
+当音符包含相应的修饰符时，渲染器会自动绘制：
+
+```typescript
+// 音符数据中包含演奏技法
+const note: JianpuNote = {
+  id: 'note-1',
+  pitch: 1,
+  duration: 1,
+  x: 100,
+  y: 60,
+  modifiers: {
+    articulations: ['staccato', 'accent'],  // 自动绘制顿音和重音
+    ornaments: ['trill'],                   // 自动绘制颤音
+    graceNotes: {                           // 自动绘制倚音
+      notes: [{ pitch: 5, octave: 0, duration: 0.25 }],
+      slash: true,
+    },
+  },
+};
+
+// 小节数据中包含反复记号
+const measure: JianpuMeasure = {
+  // ...基础属性
+  volta: { number: 1, text: '1.', type: 'start' },  // 自动绘制跳房子
+  repeatMark: { type: 'dc', text: 'D.C.' },         // 自动绘制反复标记
+};
+```

+
+## 🔧 高级用法
+
+### 自定义绘制流程
+
+```typescript
+// 获取SVG元素进行自定义操作
+const svg = renderer.getSVGElement();
+
+// 获取所有音符
+const notes = renderer.getAllNotes();
+
+// 获取所有小节
+const measures = renderer.getAllMeasures();
+
+// 使用绘制器添加自定义元素
+const dynamicsDrawer = renderer.getDynamicsDrawer();
+const customDynamic = dynamicsDrawer.drawDynamic('ff', 200, 100);
+svg?.appendChild(customDynamic);
+```
+
+### 绘制器统计
+
+每个绘制器都提供统计信息：
+
+```typescript
+const articulationDrawer = renderer.getArticulationDrawer();
+
+// 执行一些绘制操作后...
+const stats = articulationDrawer.getStats();
+console.log(`绘制数量: ${stats.articulationsDrawn}`);
+console.log(`绘制耗时: ${stats.drawTime}ms`);
+
+// 重置统计
+articulationDrawer.resetStats();
+```
+
+### OSMD兼容接口
+
+```typescript
+// 渲染器提供OSMD兼容接口
+const cursor = renderer.cursor;           // 光标适配器
+const graphicSheet = renderer.GraphicSheet;  // 图形表适配器
+const sheet = renderer.Sheet;             // 乐谱信息
+const rules = renderer.EngravingRules;    // 渲染规则
+```
+
+---
+
+## ❓ 常见问题
+
+### Q1: 如何调试渲染问题？
+
+```typescript
+// 启用调试模式
+const renderer = createJianpuRenderer(container, {
+  debug: true,  // 启用调试日志
+});
+```
+
+### Q2: 如何获取渲染性能数据？
+
+```typescript
+const stats = renderer.getStats();
+console.log(`解析时间: ${stats.parseTime}ms`);
+console.log(`布局时间: ${stats.layoutTime}ms`);
+console.log(`绘制时间: ${stats.drawTime}ms`);
+console.log(`总时间: ${stats.totalTime}ms`);
+```
+
+### Q3: 如何在已有SVG上添加新元素？
+
+```typescript
+const svg = renderer.getSVGElement();
+const dynamicsDrawer = renderer.getDynamicsDrawer();
+
+// 创建新元素
+const element = dynamicsDrawer.drawDynamic('f', 100, 80);
+
+// 添加到SVG
+svg?.appendChild(element);
+```
+
+### Q4: 绘制器配置如何更新？
+
+```typescript
+const articulationDrawer = renderer.getArticulationDrawer();
+
+// 更新绘制器配置
+articulationDrawer.updateConfig({
+  color: '#0000ff',
+});
+```

+
+### 基础用法
+
+```typescript
+import { JianpuRenderer } from '@/jianpu-renderer';
+
+// 获取容器
+const container = document.getElementById('score')!;
+
+// 创建渲染器
+const renderer = new JianpuRenderer(container);
+
+// 加载MusicXML并渲染
+await renderer.load(musicXmlString);
+renderer.render();
+```
+
+### 自定义配置
+
+```typescript
+const renderer = new JianpuRenderer(container, {
+  quarterNoteSpacing: 60,    // 四分音符间距
+  measurePadding: 25,        // 小节边距
+  systemWidth: 1000,         // 行宽度
+  noteFontSize: 22,          // 音符字体大小
+  drawLyrics: true,          // 显示歌词
+});
+```
+
+### 与业务层集成
+
+```typescript
+import { JianpuRenderer, OSMDCompatibilityAdapter } from '@/jianpu-renderer';
+
+const renderer = new JianpuRenderer(container);
+await renderer.load(xmlString);
+renderer.render();
+
+// 生成兼容OSMD的times数组
+const adapter = new OSMDCompatibilityAdapter(renderer);
+state.times = adapter.generateTimesArray();
+
+// 使用兼容接口
+const cursor = renderer.cursor;
+const graphicSheet = renderer.GraphicSheet;
+const tempo = renderer.Sheet.userStartTempoInBPM;
+```

+ * 2. 升降号处理
+ *    - 多个升降号需要避免重叠
+ *    - 水平错开排列

+ *    - 靠近各自的数字
+ * 
+ * 4. 布局规则
+ *    - 和弦宽度取决于最宽的音符

+
+## 核心模块说明
+
+### 数据模型 (models/)
 
-# 访问 http://localhost:5173
+数据模型是渲染器的核心数据结构，定义了简谱的所有元素。
+
+#### JianpuNote
+
+音符是最基本的数据单元：
+
+```typescript
+interface JianpuNote {
+  id: string;           // 唯一标识
+  pitch: number;        // 音高 1-7，0=休止符
+  octave: number;       // 八度偏移
+  duration: number;     // 时值（四分音符=1）
+  // ... 更多属性
+}
 ```
 
-### 运行测试
+关键点：
+- `duration` 使用四分音符为基准单位（1.0 = 四分音符）
+- `octave` 是相对于中央C（C4）的偏移
+- `timestamp` 是在小节内的相对位置
 
-```bash
-# 运行所有测试
-npm test
+#### JianpuMeasure
 
-# 运行测试（单次执行）
-npm run test:run
+小节包含多个声部的音符：
 
-# 运行测试（带覆盖率）
-npm run test:coverage
+```typescript
+interface JianpuMeasure {
+  voices: JianpuNote[][];  // 二维数组：[声部索引][音符索引]
+  timeSignature: { beats: number; beatType: number };
+  // ...
+}
 ```
 
----
+### 解析器 (core/parser/)
+
+#### OSMDDataParser
 
-## 📁 项目结构
+从OSMD对象提取数据，转换为简谱数据模型：
 
+```typescript
+class OSMDDataParser {
+  parse(osmd: any): JianpuScore {
+    // 遍历OSMD的Sheet.SourceMeasures
+    // 提取音符、小节信息
+    // 返回JianpuScore
+  }
+}
 ```

+
+扩展要点：
+- 处理不同的MusicXML元素时，添加相应的解析逻辑
+- 注意处理空值和边界情况
+
+#### TimeCalculator
+
+计算音符的绝对时间：
+
+```typescript
+class TimeCalculator {
+  calculateTimes(score: JianpuScore): void {
+    // 考虑BPM、拍号变化、弱起小节
+    // 计算每个音符的startTime和endTime
+  }
+}
 ```
 
----
+### 布局引擎 (core/layout/)
 
-## 🔧 核心概念
+#### MeasureLayoutEngine
 
-### 1. 数据流
+计算小节内的布局：
 
+```typescript
+class MeasureLayoutEngine {
+  layoutMeasures(measures: JianpuMeasure[]): void {
+    // 固定时间比例：相同时值的音符占据相同宽度
+    // 计算每个音符的x坐标
+    // 计算小节总宽度
+  }
+}
 ```
-MusicXML/OSMD对象
-      ↓
-  [OSMDDataParser]  解析
-      ↓
-  JianpuScore数据模型
-      ↓
-  [MeasureLayoutEngine]  布局计算
-      ↓
-  带位置信息的JianpuScore
-      ↓
-  [NoteDrawer/LineDrawer/...]  绘制
-      ↓
-  SVG DOM
-      ↓
-  [OSMDCompatibilityAdapter]  生成兼容数据
-      ↓
-  state.times数组（供业务层使用）
+
+核心算法：
+```typescript
+// 音符宽度 = 基准间距 × 时值
+noteWidth = quarterNoteSpacing * note.duration;
+
+// 小节宽度 = 左边距 + 所有音符宽度 + 右边距
+measureWidth = padding + sum(noteWidths) + padding;
 ```
 
-### 2. 时值单位
+#### SystemLayoutEngine
 
-**重要：** 整个系统使用**四分音符为单位**来表示时值。
+将小节分配到行：
 
-| 音符类型 | 时值(realValue) | 增时线数 | 减时线数 |
-|---------|----------------|---------|---------|
-| 全音符 | 4.0 | 3 | 0 |
-| 二分音符 | 2.0 | 1 | 0 |
-| 四分音符 | 1.0 | 0 | 0 |
-| 八分音符 | 0.5 | 0 | 1 |
-| 十六分音符 | 0.25 | 0 | 2 |
-| 三十二分音符 | 0.125 | 0 | 3 |
+```typescript
+class SystemLayoutEngine {
+  layoutSystems(measures: JianpuMeasure[]): { systems: JianpuSystem[] } {
+    // 根据行宽度自动换行
+    // 计算每行的Y坐标
+  }
+}
+```
 
-**增时线计算：** `Math.floor(realValue) - 1`（当 realValue >= 1）  
-**减时线计算：** `Math.round(Math.log2(1 / realValue))`（当 realValue < 1）
+### 绘制引擎 (core/drawer/)
 
-### 3. Divisions 转换
+#### NoteDrawer
 
-MusicXML中的duration需要通过divisions转换：
+绘制音符的各个组成部分：
 
 ```typescript
-// 实际时值 = duration / divisions
-const realValue = duration / divisions;
+class NoteDrawer {
+  drawNote(note: JianpuNote): SVGGElement {
+    // 1. 创建分组
+    // 2. 绘制音符数字
+    // 3. 绘制高低音点
+    // 4. 绘制附点
+    // 5. 绘制升降号
+    return group;
+  }
+}
+```
+
+#### LineDrawer
 
-// 示例（divisions=256）：
-// 四分音符：256 / 256 = 1.0
-// 八分音符：128 / 256 = 0.5
-// 二分音符：512 / 256 = 2.0
+绘制时值线：
+
+```typescript
+class LineDrawer {
+  drawDurationLines(note: JianpuNote, spacing: number): SVGGElement {
+    if (note.duration >= 2) {
+      // 绘制增时线（横线在音符右侧）
+    } else if (note.duration < 1) {
+      // 绘制减时线（下划线）
+    }
+  }
+}
 ```
 
-### 4. 音高转换
+---
+
+## 扩展开发
+
+### 添加新的修饰符类型
+
+1. 在 `JianpuNote.ts` 中扩展 `JianpuModifiers` 接口：
 
 ```typescript
-// 音名到简谱数字的映射
-const NOTE_TO_JIANPU = {
-  'C': 1, 'D': 2, 'E': 3, 'F': 4, 'G': 5, 'A': 6, 'B': 7
-};
+// 在JianpuModifiers中添加新字段
+interface JianpuModifiers {
+  // ... 现有字段
+  
+  // 新增：波音记号
+  hasWave?: boolean;
+}
+```
 
-// 八度偏移 = MusicXML octave - 4
-// octave=3 → 低音（点在下方）
-// octave=4 → 中音（无点）
-// octave=5 → 高音（点在上方）
+2. 在 `OSMDDataParser.ts` 中添加解析逻辑：
+
+```typescript
+// 在parseNoteModifiers方法中
+if (noteElement.hasWaveArticulation) {
+  modifiers.hasWave = true;
+}
 ```
 
----
+3. 在 `ModifierDrawer.ts` 中添加绘制逻辑：
 
-## 📝 编码规范
+```typescript
+// 在drawModifiersForNote方法中
+if (note.modifiers.hasWave) {
+  const waveElement = this.drawWave(note);
+  group.appendChild(waveElement);
+}
 
-### TypeScript规范
+private drawWave(note: JianpuNote): SVGElement {
+  // 绘制波音记号的SVG元素
+}
+```
 
-1. **使用严格类型**：避免使用 `any`，尽量使用具体类型
-2. **接口优先**：使用 `interface` 定义数据结构
-3. **注释完整**：每个公共方法和属性都要有JSDoc注释
-4. **命名规范**：
-   - 类名：`PascalCase` (如 `NoteDrawer`)
-   - 方法名：`camelCase` (如 `calculateWidth`)
-   - 常量：`UPPER_SNAKE_CASE` (如 `DEFAULT_SPACING`)
-   - 文件名：`PascalCase` 或 `camelCase`
+### 自定义布局策略
 
-### 代码示例
+1. 创建新的布局引擎：
 
 ```typescript
-/**
- * 计算音符的X坐标
- * @param timestamp 音符在小节中的时间戳（以四分音符为单位）
- * @param measureX 小节起始X坐标
- * @param config 渲染配置
- * @returns X坐标（像素）
- */
-function calculateNoteX(
-  timestamp: number,
-  measureX: number,
-  config: RenderConfig
-): number {
-  const { measurePadding, quarterNoteSpacing } = config;
-  return measureX + measurePadding + timestamp * quarterNoteSpacing;
+// core/layout/CustomLayoutEngine.ts
+export class CustomLayoutEngine {
+  constructor(private config: CustomLayoutConfig) {}
+  
+  layout(measures: JianpuMeasure[]): void {
+    // 自定义布局逻辑
+  }
 }
 ```
 
-### Git提交规范
+2. 在 `JianpuRenderer` 中使用：
 
-```bash
-# 格式：[任务编号] 描述
+```typescript
+// 通过配置切换布局引擎
+if (this.config.layoutMode === 'custom') {
+  this.customLayoutEngine.layout(measures);
+} else {
+  this.measureLayoutEngine.layoutMeasures(measures);
+}
+```
+
+### 添加新的输出格式
 
-# 示例：
-git commit -m "[任务1.1] 实现OSMDDataParser基础解析功能"
-git commit -m "[任务2.1] 完成小节布局计算器"
-git commit -m "[修复] 修复增时线位置计算错误"
-git commit -m "[文档] 更新API文档"
+如需输出Canvas或其他格式：
+
+```typescript
+// core/drawer/CanvasDrawer.ts
+export class CanvasDrawer {
+  private ctx: CanvasRenderingContext2D;
+  
+  constructor(canvas: HTMLCanvasElement) {
+    this.ctx = canvas.getContext('2d')!;
+  }
+  
+  drawNote(note: JianpuNote): void {
+    // 使用Canvas API绘制
+    this.ctx.fillText(String(note.pitch), note.x, note.y);
+  }
+}
 ```

-## 🚨 常见问题
+## 代码规范
 
-### Q1: divisions不同导致时值计算错误
+### TypeScript规范
 
-**问题：** 不同的MusicXML文件有不同的divisions值
+1. **类型定义**
+   - 所有公开API必须有完整的类型定义
+   - 优先使用 `interface` 而非 `type`（除非需要联合类型）
+   - 避免使用 `any`，必要时使用 `unknown`
+
+2. **命名规范**
+   ```typescript
+   // 类名：PascalCase
+   class NoteDrawer {}
+   
+   // 接口名：PascalCase，不加I前缀
+   interface JianpuNote {}
+   
+   // 方法名：camelCase
+   drawNote() {}
+   
+   // 常量：UPPER_SNAKE_CASE
+   const SVG_NS = 'http://www.w3.org/2000/svg';
+   
+   // 私有属性：前缀下划线或private关键字
+   private config: RenderConfig;
+   ```
+
+3. **文件组织**
+   - 一个文件一个主要类/接口
+   - 相关的辅助类型可以放在同一文件
+   - 导出统一通过 `index.ts`
+
+### 注释规范
 
-**解决方案：**
 ```typescript
-// ❌ 错误：直接判断duration
-if (duration === 256) { /* 四分音符 */ }
+/**
+ * 音符绘制器
+ * 
+ * @description 负责绘制简谱音符的所有可视元素
+ * 
+ * @example
+ * const drawer = new NoteDrawer(config);
+ * const element = drawer.drawNote(note);
+ */
+export class NoteDrawer {
+  /**
+   * 绘制音符
+   * @param note 要绘制的音符
+   * @returns SVG分组元素
+   */
+  drawNote(note: JianpuNote): SVGGElement {
+    // ...
+  }
+}
+```
+
+### Git提交规范
 
-// ✅ 正确：先转换为相对时值
-const realValue = duration / divisions;
-if (realValue === 1.0) { /* 四分音符 */ }
+```
+feat: 添加波音记号绘制功能
+fix: 修复多声部对齐问题
+docs: 更新API文档
+refactor: 重构布局引擎
+test: 添加性能测试
+chore: 更新依赖版本
 ```
 
-### Q2: 增时线位置不正确
+---
 
-**问题：** 增时线应该按四分音符间距均匀分布
+## 贡献流程
 
-**解决方案：**
-```typescript
-// 二分音符（2拍）的增时线应该在第2拍的位置
-const extensionLineX = noteX + quarterNoteSpacing;
+### 1. 创建Issue
 
-// 全音符（4拍）的3条增时线
-for (let i = 1; i <= 3; i++) {
-  const lineX = noteX + i * quarterNoteSpacing;
-  drawExtensionLine(lineX);
-}
+在开始开发前，先创建Issue描述要解决的问题或要添加的功能。
+
+### 2. 创建分支
+
+```bash
+git checkout -b feature/add-wave-ornament
+# 或
+git checkout -b fix/multi-voice-alignment
 ```
 
-### Q3: 多声部对齐问题
+### 3. 开发和测试
 
-**问题：** 同一时间点的不同声部音符X坐标不一致
+```bash
+# 开发时运行测试
+npx vitest watch
 
-**解决方案：**
-使用 `MultiVoiceAligner` 统一分配X坐标：
-```typescript
-// 收集所有时间戳
-const timestamps = collectAllTimestamps(measure);
+# 提交前确保所有测试通过
+npx vitest run
+```
 
-// 为每个时间戳分配唯一的X坐标
-const timestampToX = new Map<number, number>();
-timestamps.forEach((ts, index) => {
-  timestampToX.set(ts, calculateX(ts));
-});
+### 4. 提交代码
 
-// 更新所有声部的音符X坐标
-measure.voices.forEach(voice => {
-  voice.forEach(note => {
-    note.x = timestampToX.get(note.timestamp)!;
-  });
-});
+```bash
+git add .
+git commit -m "feat: 添加波音记号绘制功能"
 ```
 
+### 5. 创建Pull Request
+

+```typescript
+import { JianpuRenderer } from '@/jianpu-renderer';
+
+// 获取容器
+const container = document.getElementById('score')!;
+
+// 创建渲染器并渲染
+const renderer = new JianpuRenderer(container);
+await renderer.load(musicXmlString);
+renderer.render();
+```
+
+### 示例2：带配置的渲染
+
+```typescript
+import { JianpuRenderer } from '@/jianpu-renderer';
+
+const container = document.getElementById('score')!;
+
+// 自定义配置
+const renderer = new JianpuRenderer(container, {
+  quarterNoteSpacing: 60,    // 音符间距
+  measurePadding: 25,        // 小节边距
+  systemWidth: 1000,         // 行宽度

+  drawLyrics: true,          // 显示歌词
+});
+
+await renderer.load(musicXmlString);
+renderer.render();
+
+// 获取渲染统计
+const stats = renderer.getStats();
+console.log(`渲染完成: ${stats.noteCount}个音符, ${stats.measureCount}个小节`);
+console.log(`总耗时: ${stats.totalTime.toFixed(2)}ms`);
+```
+
+### 示例3：从文件加载
+
+```typescript
+import { JianpuRenderer } from '@/jianpu-renderer';
+
+async function loadAndRender(filePath: string) {
+  // 加载MusicXML文件
+  const response = await fetch(filePath);

+  const renderer = new JianpuRenderer(container);
+  await renderer.load(xmlString);
+  renderer.render();
+  
+  return renderer;
+}
+
+// 使用
+loadAndRender('/scores/sample.xml');
+```
+
+---
+
+## 配置示例
+
+### 示例4：紧凑布局（适合长曲谱）
+
+```typescript
+const renderer = new JianpuRenderer(container, {
+  quarterNoteSpacing: 35,    // 减小间距
+  measurePadding: 15,        // 减小边距
+  noteFontSize: 16,          // 减小字体
+  lyricFontSize: 12,         // 减小歌词字体
+  systemWidth: 1200,         // 增加行宽度
+});
+```
+
+### 示例5：宽松布局（适合教学）
+
+```typescript
+const renderer = new JianpuRenderer(container, {
+  quarterNoteSpacing: 80,    // 增大间距
+  measurePadding: 35,        // 增大边距
+  noteFontSize: 28,          // 增大字体
+  lyricFontSize: 18,         // 增大歌词字体
+  systemWidth: 700,          // 减小行宽度
+});
+```
+
+### 示例6：移动端自适应
+
+```typescript
+function createResponsiveRenderer(container: HTMLElement) {
+  const width = window.innerWidth;
+  const isMobile = width < 768;
+  
+  return new JianpuRenderer(container, {
+    quarterNoteSpacing: isMobile ? 35 : 50,
+    measurePadding: isMobile ? 15 : 20,
+    noteFontSize: isMobile ? 16 : 20,
+    systemWidth: Math.min(width - 40, 1000),
+    drawLyrics: true,
+  });
+}
+
+// 响应窗口大小变化
+let renderer = createResponsiveRenderer(container);
+await renderer.load(xmlString);
+renderer.render();
+
+window.addEventListener('resize', () => {
+  const width = window.innerWidth;

+    noteFontSize: width < 768 ? 16 : 20,
+    systemWidth: Math.min(width - 40, 1000),
+  });
+});
+```
+
+### 示例7：自定义颜色主题
+
+```typescript
+// 暗色主题
+const darkTheme = {
+  noteColor: '#e0e0e0',
+  lyricColor: '#b0b0b0',
+  lineColor: '#808080',
+};
+
+// 彩色主题
+const colorTheme = {

+### 示例13：与业务状态集成
+
+```typescript
+import { JianpuRenderer, OSMDCompatibilityAdapter } from '@/jianpu-renderer';
+
+// 假设这是业务状态
+const state = {
+  times: [] as TimeEntry[],
+  activeNoteIndex: -1,
+};
+
+async function initWithBusinessState(container: HTMLElement, xml: string) {
+  const renderer = new JianpuRenderer(container);

+  renderer.render();
+  
+  // 生成兼容数据
+  const adapter = new OSMDCompatibilityAdapter(renderer);
+  state.times = adapter.generateTimesArray();
+  
+  // 使用OSMD兼容接口
+  const cursor = renderer.cursor;
+  const graphicSheet = renderer.GraphicSheet;
+  const tempo = renderer.Sheet.userStartTempoInBPM;
+  
+  console.log('业务状态已同步:', {
+    timesCount: state.times.length,
+    tempo,
+  });
+  
+  return renderer;
+}
+```

+
+## 快速开始
+
+### 1. 导入渲染器
+
+```typescript
+import { JianpuRenderer } from '@/jianpu-renderer';
+```
+
+### 2. 准备容器
+
+```html
+<div id="score-container" style="width: 100%; min-height: 400px;"></div>
+```
+
+### 3. 创建并渲染
+
+```typescript
+// 获取容器
+const container = document.getElementById('score-container')!;
+
+// 创建渲染器
+const renderer = new JianpuRenderer(container);
+
+// 加载MusicXML数据
+await renderer.load(musicXmlString);
+
+// 渲染
+renderer.render();
+```
+
+**完成！** 简谱已渲染到容器中。
+
+---
+
+## 基本用法
+
+### 加载数据
+
+简谱渲染器支持两种数据源：
+
+#### 方式1：加载MusicXML字符串
+
+```typescript
+const xmlString = `<?xml version="1.0" encoding="UTF-8"?>
+<score-partwise>
+  <!-- MusicXML内容 -->
+</score-partwise>`;
+
+await renderer.load(xmlString);
+```
+
+#### 方式2：加载OSMD对象
+
+如果您已有OpenSheetMusicDisplay对象，可以直接传入：
+
+```typescript
+const osmd = new OSMD.OpenSheetMusicDisplay(container);
+await osmd.load(xmlString);
+
+// 传入OSMD对象
+await renderer.load(osmd);
+```
+
+### 渲染控制
+
+```typescript
+// 渲染曲谱
+renderer.render();
+
+// 获取渲染统计
+const stats = renderer.getStats();
+console.log(`音符数: ${stats.noteCount}`);
+console.log(`小节数: ${stats.measureCount}`);
+console.log(`渲染耗时: ${stats.totalTime}ms`);
+```
+
+### 获取数据
+
+```typescript
+// 获取所有音符
+const notes = renderer.getAllNotes();
+
+// 获取所有小节
+const measures = renderer.getAllMeasures();
+
+// 获取速度
+const tempo = renderer.getTempo();
+
+// 获取Score对象
+const score = renderer.getScore();
+
+// 获取SVG元素
+const svg = renderer.getSVGElement();
+```
+
+---
+
+## 配置选项
+
+### 初始化配置
+
+在创建渲染器时传入配置：
+
+```typescript
+const renderer = new JianpuRenderer(container, {
+  // 布局配置
+  quarterNoteSpacing: 60,    // 四分音符间距（越大音符越分散）
+  measurePadding: 25,        // 小节左右边距
+  systemWidth: 1000,         // 行宽度
+  systemHeight: 150,         // 行高度
+  
+  // 显示配置
+  drawLyrics: true,          // 是否显示歌词
+  drawPartNames: false,      // 是否显示声部名称
+  
+  // 样式配置
+  musicColor: '#333333',     // 音符颜色
+  noteFontSize: 22,          // 音符字体大小
+  fontFamily: 'Arial',       // 字体
+});
+```
+
+### 动态更新配置
+
+```typescript
+// 更新部分配置
+renderer.updateConfig({
+  quarterNoteSpacing: 70,
+  noteColor: '#0066cc',
+});
+// 自动重新渲染
+```
+
+### 常用配置场景
+
+#### 紧凑布局（适合长曲谱）
+
+```typescript
+renderer.updateConfig({
+  quarterNoteSpacing: 35,
+  measurePadding: 15,
+  noteFontSize: 18,
+});
+```
+
+#### 宽松布局（适合教学展示）
+
+```typescript
+renderer.updateConfig({
+  quarterNoteSpacing: 80,
+  measurePadding: 30,
+  noteFontSize: 24,
+});
+```
+
+#### 移动端适配
+
+```typescript
+const isMobile = window.innerWidth < 768;
+renderer.updateConfig({
+  quarterNoteSpacing: isMobile ? 35 : 50,
+  noteFontSize: isMobile ? 16 : 20,
+  systemWidth: isMobile ? window.innerWidth - 20 : 800,
+});
+```
+
+---
+
+## 高级功能
+
+### 响应式布局
+
+```typescript
+function handleResize() {
+  const width = window.innerWidth;
+  
+  renderer.updateConfig({
+    systemWidth: Math.min(width - 40, 1200),
+    quarterNoteSpacing: width < 600 ? 35 : 50,
+    noteFontSize: width < 600 ? 16 : 20,
+  });
+}
+
+window.addEventListener('resize', handleResize);
+```
+
+### 性能监控
+
+```typescript
+import { PerformanceProfiler } from '@/jianpu-renderer/utils';
+
+const profiler = new PerformanceProfiler();
+
+// 监控加载性能
+profiler.start('load');
+await renderer.load(xmlString);
+const loadTime = profiler.end('load');
+
+// 监控渲染性能
+profiler.start('render');
+renderer.render();
+const renderTime = profiler.end('render');
+
+console.log(`加载耗时: ${loadTime}ms`);
+console.log(`渲染耗时: ${renderTime}ms`);
+
+// 获取完整报告
+console.log(profiler.getReport());
+```
+
+### 批量渲染优化
+
+对于大量音符的渲染，使用批量渲染可以提升性能：
+
+```typescript
+import { BatchRenderer, SVGHelper } from '@/jianpu-renderer/utils';
+
+const batch = new BatchRenderer();
+
+// 批量创建元素
+for (const note of notes) {
+  const text = SVGHelper.createText(note.x, note.y, String(note.pitch), 20);
+  batch.add(text);
+}
+
+// 一次性刷新到DOM（减少重排）
+batch.flush(svgContainer);
+```
+
+### 自定义样式
+
+通过CSS自定义渲染样式：
+
+```css
+/* 音符样式 */
+.vf-note {
+  cursor: pointer;
+}
+
+.vf-note:hover {
+  fill: #0066cc;
+}
+
+/* 当前播放高亮 */
+.vf-note.active {
+  fill: #ff6600;
+}
+
+/* 歌词样式 */
+.vf-lyric {
+  font-family: "Microsoft YaHei", sans-serif;
+}
+
+/* 小节线样式 */
+.vf-barline {
+  stroke: #666;
+  stroke-width: 1;
+}
+
+/* 减时线（下划线）样式 */
+.vf-underline {
+  stroke: #000;
+  stroke-width: 1.5;
+}
+```
+
+### 音符高亮
+
+```typescript
+// 高亮指定音符
+function highlightNote(noteId: string) {
+  const svg = renderer.getSVGElement();
+  if (!svg) return;
+  
+  // 移除之前的高亮
+  svg.querySelectorAll('.vf-note.active').forEach(el => {
+    el.classList.remove('active');
+  });
+  
+  // 添加新高亮
+  const noteEl = svg.querySelector(`#vf-${noteId}`);
+  if (noteEl) {
+    noteEl.classList.add('active');
+  }
+}
+
+// 播放时高亮
+function onPlaybackProgress(currentTime: number) {
+  const notes = renderer.getAllNotes();
+  const currentNote = notes.find(n => 
+    currentTime >= n.startTime && currentTime < n.endTime
+  );
+  
+  if (currentNote) {
+    highlightNote(currentNote.id);
+  }
+}
+```
+
+---
+
+## 与业务层集成
+
+### 生成兼容数据
+
+简谱渲染器提供与OSMD兼容的接口，方便与现有业务代码集成：
+
+```typescript
+import { JianpuRenderer, OSMDCompatibilityAdapter } from '@/jianpu-renderer';
+
+// 创建渲染器
+const renderer = new JianpuRenderer(container);
+await renderer.load(xmlString);
+renderer.render();
+
+// 创建兼容适配器
+const adapter = new OSMDCompatibilityAdapter(renderer);
+
+// 生成times数组（与原OSMD格式完全兼容）
+const times = adapter.generateTimesArray();
+
+// 赋值给业务状态
+state.times = times;
+
+// 使用cursor接口
+const cursor = renderer.cursor;
+cursor.show();
+cursor.next();
+
+// 使用GraphicSheet接口
+const graphicSheet = renderer.GraphicSheet;
+```
+
+### 在Vue组件中使用
+
+```typescript
+// composables/useJianpuRenderer.ts
+import { ref, onMounted, onUnmounted } from 'vue';
+import { JianpuRenderer } from '@/jianpu-renderer';
+
+export function useJianpuRenderer() {
+  const renderer = ref<JianpuRenderer | null>(null);
+  const containerRef = ref<HTMLElement | null>(null);
+  
+  const init = async (xml: string) => {
+    if (!containerRef.value) return;
+    
+    renderer.value = new JianpuRenderer(containerRef.value, {
+      quarterNoteSpacing: 50,
+      drawLyrics: true,
+    });
+    
+    await renderer.value.load(xml);
+    renderer.value.render();
+  };

+      
+      // 滚动到可见区域
+      scrollToNote(currentNote);
+    }
+  });
+}
+
+function scrollToNote(note: JianpuNote) {
+  const svg = renderer.getSVGElement();
+  const container = svg?.parentElement;
+  
+  if (container) {
+    const noteTop = note.y;
+    const containerHeight = container.clientHeight;
+    const scrollTop = noteTop - containerHeight / 2;
+

+      behavior: 'smooth',
+    });
+  }
+}
+```

+
+## 常见问题
+
+### Q1: 渲染后音符重叠怎么办？
+
+**A:** 增加 `quarterNoteSpacing` 值或减小 `systemWidth`：
+
+```typescript
+renderer.updateConfig({
+  quarterNoteSpacing: 70,  // 增大间距
+});
+```
+
+### Q2: 如何处理超长曲谱？
+
+**A:** 使用紧凑配置，并确保容器有足够的滚动空间：
+
+```typescript
+renderer.updateConfig({
+  quarterNoteSpacing: 35,
+  measurePadding: 15,
+  noteFontSize: 16,
+});
+```
+
+```css
+.score-container {
+  max-height: 600px;
+  overflow-y: auto;
+}
+```
+
+### Q3: 如何自定义音符颜色？
+
+**A:** 通过配置或CSS：
+
+```typescript
+// 方式1: 配置
+renderer.updateConfig({
+  noteColor: '#0066cc',
+});
+
+// 方式2: CSS
+```
+
+```css
+.vf-note text {
+  fill: #0066cc !important;
+}
+```
+
+### Q4: 歌词显示不全怎么办？
+
+**A:** 检查歌词字体配置，确保支持中文：
+
+```typescript
+renderer.updateConfig({
+  lyricFontFamily: '"Microsoft YaHei", "Noto Sans SC", sans-serif',
+  lyricFontSize: 16,
+});
+```
+
+### Q5: 如何获取音符的DOM元素？
+
+**A:** 使用音符ID查询：
+
+```typescript
+const notes = renderer.getAllNotes();
+const svg = renderer.getSVGElement();
+
+for (const note of notes) {
+  const element = svg?.querySelector(`#vf-${note.id}`);
+  if (element) {
+    // 操作DOM元素
+    element.addEventListener('click', () => {
+      console.log('点击了音符:', note.pitch);
+    });
+  }
+}
+```
+
+### Q6: 如何处理不同拍号的曲谱？
+
+**A:** 简谱渲染器自动处理拍号变化，每个小节都会保存拍号信息：
+
+```typescript
+const measures = renderer.getAllMeasures();
+for (const measure of measures) {
+  console.log(`小节${measure.measureNumber}: ${measure.timeSignature.beats}/${measure.timeSignature.beatType}`);
+}
+```
+
+### Q7: 渲染性能不佳怎么优化？
+
+**A:** 使用性能分析工具定位瓶颈：
+
+```typescript
+import { PerformanceProfiler } from '@/jianpu-renderer/utils';
+
+const profiler = new PerformanceProfiler();
+profiler.start('render');
+renderer.render();
+const time = profiler.end('render');
+
+if (time > 100) {
+  console.warn('渲染耗时较长，考虑优化配置');
+  // 减少systemWidth可以减少每行音符数
+  renderer.updateConfig({
+    systemWidth: 600,
+  });
+}
+```
