+如何让这堆代码变成可以浏览的网站？
+
+1. 下载
+
+ 如果你正在GitHub上读这段文字，你可以用下面的git命令下载源代码（请将git clone后面的地址替换成你在浏览器地址栏中看到的实际地址）
+
+ git clone https://github.com/renfeng/devfest2014
+
+ 如果你不用git，也可以找到“Download ZIP”按钮，点一下，将原文件打包下载。
+
+2. 安装
+
+ 不需要安装特殊的服务器软件。所有文件都是静态的（相对服务器端而言）。但是，需要安装一个特殊的目录，bower_components。
+
+ 而安装这个目录，需要执行下面的一行命令（先别急着执行，请继续向下读）
+
+ bower install
+
+ 要执行上一行命令，需要先执行
+
+ npm install -g bower
+
+ 要执行上一行命令，需要先安装nodejs。见http://nodejs.org
+
+3. 为了用Google Map，需要为你的域名设置专用的api key。
+
+4. 将代码放在任何网站服务器下面，例如Apache HTTPd。
+
+代码是从https://github.com/gdgbeijing/devfest2014 复制来的。下面是原作者的readme
