+
+## 概述
+    框架命名( Hood )  发动机罩引擎罩来源于Yohood, 框架基于 Yaf 在数据层封装了Dao、Cache、Concurrent、Debug、Server 6个主要模块
+框架以简单快捷为目的.
+
+## 安装
+      php版本要求 php 5.4+ 以上版本, 必要模块 Pdo_MySQL、Yaf、Yar
+      https://github.com/laruence/php-yaf
+      https://github.com/laruence/yar
+
+      Yaf 文档 
+      http://php.net/manual/zh/book.yaf.php
+
+## 配置文件
+     1、数据库配置
+
+     [mysql]
+     charset = UTF8
+     persistent = TRUE
+     collation = utf8_unicode_ci
+     timeout = 3
+     [database]
+     erp_admin.username = root
+     erp_admin.passwd = root
+     erp_admin.write = 127.0.0.1:3306
+     erp_admin.read = 192.168.1.106:3306
+     erp_admin.dbname = erp_admin
+
+     hood.username = root
+     hood.passwd = root
+     hood.write = 127.0.0.1:3306
+     hood.read = 192.168.1.106:3306
+
+     hood2.username = root
+     hood2.passwd = root
+     hood2.write = 127.0.0.2:3306
+     hood2.read = 192.168.2.106:3306
+ 
+
+     
+     2、缓存配置
+     [memcached]
+     servers.hosts = 127.0.0.1:11211:90,127.0.0.1:11212:10
+     erp.hosts = 127.0.0.1:11211:90,127.0.0.1:11212:106
+     [redis]
+     servers.hosts = 127.0.0.1:6379
+
+
+## Dao 
+    Dao 提供主要如下方法
+   
+    1、数据操作
+      insert、delete、update
+
+      2、查询数据
+      fetchAll、fetchRow、fetchPairs、fetchOne、fetchColumn、fetchObject、fetchClassRow、fetchClass、fetchAssoc、
+     
+      3、其他设置
+      setModality        设置读写服务器
+      cache                 缓存设置
+      tag                      缓存标签
+      key                      缓存key
+      expire                  缓存过期时间
+
+     数据库操作借鉴Java的 mybatis 把SQL已配置文件形式存储
+     class SqlMap
+     {
+         const INSERT_DEMO = 'insert into demo (`username`,`email`) values (:username,:email)';
+         const UPDATA_DEMO_BY_ID = 'update demo set `username`=:username,`email`=:email where `id`=:id';
+         const SELECT_DEMO_BY_ID = 'select * from `demo` where id=:id';
+     }
+          
+         Insert 
+     $this->dao()->insert(SqlMap::INSERT_DEMO, array(
+         'username' => $username,
+         'email' => $email
+     ))->lastInsertId();
+
+          setModality(设置读写模式)
+     $this->dao()->setModality('read')->insert(SqlMap::INSERT_DEMO, array(
+         'username' => $username,
+         'email' => $email
+     ))->lastInsertId();
+
+         update
+     $this->dao()->tag('demo_' . $id)->update(SqlMap::UPDATA_DEMO_BY_ID, array(
+         'username' => $username,
+         'email' => $email,
+         'id' => $id
+     ))->rowCount();
+
+     fetchClassRow
+     $this->dao()->tag('demo_' . $id)->key('demo_row')->expire(300)->setFetchClass('Models\Hood\Demo\Form')
+     ->fetchClassRow(SqlMap::SELECT_DEMO_BY_ID, array( 'id' => $id ));
+     
+     fetchAssoc
+     $this->dao()->tag('demo_' . $id)->key('demo_info')->fetchAssoc(SqlMap::SELECT_DEMO_BY_ID, array('id' => $id));
+
+
+## Cache
+    
+     $mc = hoodCache::Memcached($node, $child_node);
+     $mc->add($key , $val);
+     hoodCache::Memcached()->get($key);
+     hoodCache::Redis()->get($key);
+
+
+## Concurrent
+1、RPC ( PHP )
+    
+    1、普通接口数据请求
+    Concurrent::yarClient($uri)->getDemoInfoByID($id);
+
+    2、平行数据请求
+    Concurrent::yarConcurrent($uri)->calls('getDemoInfoByID', 1,function ($demoData) {
+                       xxxx
+    })->calls('getDemoInfoByID', 2,function ($demoData) {
+                       xxxxx
+    })->loop();
+
+2、CURL Concurrent
+
+    ```php
         use Hood\Concurrent;
         $CurlMulti = Concurrent::curlMulti();
         $CurlMulti->call('http://www.baidu.com',function ($curl_info, $curl_data, $callback_data) {
@@ -14,4 +135,6 @@
         $CurlMulti->callRest('http://www.qin.com/index/demo', 'get', function ($curl_info, $curl_data, $callback_data) {
             print_r($curl_data);
         }, array('a' => 1))->finish();
