This plugin adds to Profile Pages an extended “Author Bio”. This allows users to add more information to what they’d feel comfortable adding underneath the post. This Author Bio can be displayed on the author page, as opposed to the standard “Author Description”.
This plugin is a framework, so requires a bit of PHP skill and experience in template editing to make it work.

<h3>Usage Instructions</h3>
The best place to use this plugin is on the author.php page. I have included a framework for using this plugin.
To begin with, on <code>author.php</code>, add this line. This will get the information on the author.
<pre><code>$author = wp_authorplus_get_user_on_author_page();
</code></pre>
You can then use the standard <code>echo $author->display_name;</code> and similar notation as shown in (The WordPress Codex)[https://codex.wordpress.org/Author_Templates#Using_Author_Information].
To call the extended author descriptions, use <code><?php wp_authorplus_extended_author_bio($author->ID); ?></code> anywhere outside the WordPress Loop, but after you declare $author on wp_authorplus_get_user_on_author_page().
