<p>WP Head Footer allows you to easily add custom code to the header and/or footer of any post,<br />
page, or custom post type on your WordPress site without modifying theme files.<br />
You can add JavaScript, HTML, CSS, and unleash your creativity to take your website to the next level.</p>
<h4>Installation</h4>
<p>To install the WP Head Footer plugin, follow these steps:</p>
<p>Upload the WP Head Footer plugin to the /wp-content/plugins/ directory of your WordPress site, or install it through the WordPress admin area.<br />
Activate the plugin from the WordPress plugins screen.</p>
<h4>Usage</h4>
<p>To start adding your custom code at a global level or for individual posts/pages, follow these steps:</p>
<p>Go to the WP Head Footer settings page.<br />
Add your custom code in the provided fields.</p>
<h4>Notes</h4>
<p>If the metabox is not displayed, you can manually add support by using the “add_post_type_support”<br />
function with the key “wp-head-footer”. Here’s an example:<br />
    add_action(‘init’, ‘my_custom_post_type_support’);<br />
    function my_custom_post_type_support() {<br />
        add_post_type_support(‘your_custom_post_type’, ‘wp-head-footer’);<br />
    }</p>
<p>If you are using third-party plugins like ACF or CPT UI to create the post type,<br />
you can directly add support for WP Head Footer there.<br />
Please note that using this plugin requires “manage_options” capability. Also, exercise caution when adding custom code to your site, as the plugin does not provide input validation or filtering.</p>
