+## 字符打乱
+`puck`可以支持生成添加干扰符号，字符码等的变形字体，以实现个性的效果。　
+
+## 用法
+
+### 基本用法
+```php
+use puck\helpers\Chaos;
+$s='你好';
+$chaos = new Chaos(); 
+        $prefix=[
+            '[微笑]',
+            '[大笑]',
+            '[色]',
+            '[失望]',
+            '[皱眉]',
+            '[哭]',
+            '[惊恐]',
+            '[亲亲]',
+            '[大眼]',

+## 拼音扩展
+`puck`支持中文和拼音间的转换，对地名，人名，句子等均有处理，它甚至能支持音调的携带。  
+这个扩展库由[https://github.com/overtrue/pinyin](https://github.com/overtrue/pinyin)提供技术支持。 
+
+## 用法
+
+### 基本用法
+```php
+use puck\helpers\Pinyin;
+$pinyin = new Pinyin(); 
+$pinyin->convert('带着希望去旅行，比到达终点更美好');
+// ["dai", "zhe", "xi", "wang", "qu", "lv", "xing", "bi", "dao", "da", "zhong", "dian", "geng", "mei", "hao"]
+$pinyin->convert('带着希望去旅行，比到达终点更美好', PINYIN_UNICODE);
+// ["dài","zhe","xī","wàng","qù","lǚ","xíng","bǐ","dào","dá","zhōng","diǎn","gèng","měi","hǎo"]
+
+$pinyin->convert('带着希望去旅行，比到达终点更美好', PINYIN_ASCII);
+//["dai4","zhe","xi1","wang4","qu4","lv3","xing2","bi3","dao4","da2","zhong1","dian3","geng4","mei3","hao3"]
+
+```
+
+### 生产用于链接
+
+```php
+$pinyin->permalink('带着希望去旅行'); // dai-zhe-xi-wang-qu-lv-xing
+$pinyin->permalink('带着希望去旅行', '.'); // dai.zhe.xi.wang.qu.lv.xing
+```
+
+### 获取首字符
+
+```php
+$pinyin->abbr('带着希望去旅行'); // dzxwqlx
+$pinyin->abbr('带着希望去旅行', '-'); // d-z-x-w-q-l-x
+```
+
+### 生成句子
+
+```php
+$pinyin->sentence('带着希望去旅行，比到达终点更美好！');
+// dai zhe xi wang qu lv xing, bi dao da zhong dian geng mei hao!
+
+$pinyin->sentence('带着希望去旅行，比到达终点更美好！', true);
+// dài zhe xī wàng qù lǚ xíng, bǐ dào dá zhōng diǎn gèng měi hǎo!
+```
+
+### 翻译姓名
+
+```php
+$pinyin->name('单某某'); // ['shan', 'mou', 'mou']
+$pinyin->name('单某某', PINYIN_UNICODE); // ["shàn","mǒu","mǒu"]
+```
+
+### 专用名词
+
+```php
+$pinyin->noun('山西'); // ShanXi
+```
