+# ph-Bookshelf
+
+一个基于 Gitbook 的简单的多 book 实现。
+
+因为 web 相关的东西 Sukazyo 最熟悉的就是 php 了所以就用 php 写的。
+但是写出来的代码还是十分离谱的不易读的：各种调用交错在一起，前后端也交错在一起
+
+而且也并不好用，不好用到几乎没办法写教程...那种...至少现在如此。
+
+有时间的话会补充的（en
+
+<br/>
+
+### 安装
+
+下载/clone此仓库的内容，然后拖进 php 站点根目录。
+
+对于 Apache（即 .htaccess 支持的 php 环境），可以直接运行。
+
+对于 Nginx 或者别的之类的 php 环境，需要转换一下伪静态配置，以 .htaccess 文件内的内容为依据即可。
+
+<br/>
+
+### 使用
+
+未来可能会拖出来一个示例之类的...
+
+<br/>
+
+### 开源许可
+
+本软件的代码（因为写得真的不好所以）开源于公共领域，<br/>
+（但显然 Gitbook (/assets/gitbook/*) 中的内容还是受限于 Apache 2.0 的）
