引言： 终于有时间把以前的想要学(其实早就该学)的知识进行整理学习，不想花太多时间，但又不得花多的时间，废话少说加油吧！
Thanks! Alessandro Castellani !

第一节内容：主要讲解了WordPress的目录结构，只需要关心wp-content目录即可
wp-content/themes 和 wp-content/plugins 分别对应着主题和插件
开发环境开启：
1. 开启开发环境：首先需要打开debug参数开关，在根目录的wp-config.php文件中 修改为
define(‘WP_DEBUG’, true);
然后进入主题文件夹 wp-content/themes 创建自己的主题目录 比如 z
2. 创建2个必要结构文件：
第1个重要的识别文件 style.css 内容要按照标准再顶部加入注释格式
/*
Theme Name: z
Theme URI: https://wordpress.org/themes/twentyseventeen/

第2个重要的模板文件index.php
<?php get_header(); ?>

<?php get_footer(); ?>
3. 创建模板头尾部文件header.php footer.php
Super easy! Super beginer beginer!
