The process of developing a simple plugin is not complex. It follows the same process we used for themes, where we used PHP header comments. First, you have to create a new directory inside wp-content/plugins, with a preferred name. In this example, we are going to name it wpquick-after-post-content. Once the plugin directory has been created, we can create the main plugin file, which is wpquick-after-post-content.php. You can use the preferred name for the main plugin file. Now, we have to add the following header comments section to define it as a plugin:
<?php/*Plugin Name: WPQAPC After Post ContentPlugin URI: http://www.wpexpertdeveloper.com/wpquick-after-postDescription: Add dynamic content after the post
