humans.txt is an initiative for knowing the people behind a website. It’s a text file that lists the people who contributed to building the site – developers, designers, and others. Think of it as the opposite of robots.txt: robots.txt is for machines, humans.txt is for people.
MTDEV Humans TXT lets you create and edit your site’s humans.txt file straight from the WordPress dashboard, without touching code or uploading files over FTP.
The file is served virtually at your site root (<code>https://your-site.com/humans.txt</code>) through rewrite rules, so it needs no write permissions and no physical file is created. It also adds the recommended <code>rel="author"</code> link to your site’s <code><head></code>, pointing to your humans.txt file.
Features:
<ul>
<li>Content editor with a default template based on the standard (TEAM, THANKS, SITE).</li>
<li>Virtual <code>/humans.txt</code> served as <code>text/plain</code>.</li>
<li>Option to enable or disable the <code><head></code> link.</li>
<li>No physical files, multisite friendly.</li>
<li>Makes no external server calls.</li>
<li>Translation ready (text domain <code>mtdev-humans-txt</code>).</li>
</ul>

<h3>Shortcode Usage</h3>
The default shortcode <code>[humanstxt]</code> will display the contents of the virtual humans.txt file. URLs, email addresses and Twitter account names are converted into clickable links. Plain email addresses are encoded for spam protection. The output will be wrapped with a <code></code> tag and can be styled via the <code>humanstxt</code> CSS class.
You can turn off the “clickable links” functionality: <code>[humanstxt clickable="0"]</code>
You can also toggle the clickable links individually: <code>[humanstxt urls="1" emails="0" twitter="1"]</code>
To display the humans.txt as preformatted text, use the <code>pre</code> attribute: <code><pre>[humanstxt pre="1"]</pre></code>
To display the untouched humans.txt, use the <code>plain</code> attribute: <code>[humanstxt plain="1"]</code>
You can omit the wrapping with the <code></code> tag: <code>[humanstxt wrap="0"]</code>
You can set a CSS id for the wrapping <code></code> tag: <code>[humanstxt id="my-humans-txt"]</code>
You can turn off the encoding of email addresses and common text entities: <code>[humanstxt filter="0"]</code>
