 2 | HProxy powered by PHP

 4 | # 使用教程
 5 | 1.登录Github，先将这个 repo Fork到自己的帐号里（右上角）
 6 | 
 7 | 2.打开[heroku](https://www.heroku.com/)， 点击[注册(Sign Up)](https://signup.heroku.com/)，注册一个帐号   
 8 | 
 9 | 3.登陆之后默认就在[app面板](https://dashboard.heroku.com/apps)，点击右上角的News-Create new app    
10 | 
11 | 4.然后输入名字，第二个选项是服务器所在位置，默认的美国不用改  
12 | 
13 | 5.创建好之后，默认应该打开的是Deploy(部署) 选项卡，在Deployment method处选Github，登录并关联自己的Github帐号   
14 | 
15 | 6.在Connect to GitHub这一栏，搜索HProxy，然后选中这个repo   
16 | 
17 | 7.在最下面的Manual deploy这一栏，选中master，然后点Deploy Branch    
18 | 
19 | 8.完成，接下来只要在应用的HProxy设置中填上这个app的地址（默认为https://<你填的名字>.herokuapp.com/）
