Enabling commenting on my Tumblr

Many Tumblr themes have either the <a href="https://disqus.com">Disqus commenting platform</a> or <a href="https://developers.facebook.com/docs/plugins/comments/">Facebook commenting</a>&nbsp;built into them. If they don&#39;t, enabling Disqus commenting for Tumblr is especially simple thanks to their awesome <a href="https://disqus.com/admin/tumblr/">Disqus install instructions for Tumblr</a>.<br />

<br />
<a href="http://pixelunion.wpengine.com/themes/tumblr">All of our Tumblr themes</a>&nbsp;have Disqus or Facebook commenting built in, and many other themes have similar customization options to set them up.
<h3>Disqus comments</h3>
You can enable Disqus comments in your theme customization options by filling in your <strong>Disqus Shortname&nbsp;</strong>for your site. You will need to set up the Disqus shortname for your site from your <a href="http://disqus.com">Disqus</a> account.
<h3>Facebook comments</h3>
<em>If these directions don&#39;t match what you are seeing, Facebook may have changed their setup method &ndash; and we&#39;d love it if you could <a href="http://help.pixelunion.net/customer/portal/emails/new">send us a message</a> and let us know. And if at any point you feel lost, don&#39;t hesitate to get in contact!</em><br />
<br />
Setting up Facebook comments requires a bit more time, but can be well worth it because, well, it&#39;s Facebook integration. First, make sure the&nbsp;<strong>Facebook comments</strong><em>&nbsp;</em>toggle is enabled in your customization settings. Next, you will need to retrieve <strong>Facebook API ID</strong>, which will allow you to connect your site to a unique Facebook comments board.<br />
<br />
<a href="https://developers.facebook.com/apps">Set up a Facebook App</a>&nbsp;and give your app a name. You may receive an error when entering a security check, but you should be able to continue anyway. Click on the&nbsp;<strong>Getting started&nbsp;</strong>link in your new app&#39;s dashboard, choose the&nbsp;<strong>Website</strong> platform, and fill in your site&#39;s URL in the <b>Tell us about your site</b> section. After clicking the&nbsp;<strong>Next</strong>&nbsp;button, you can scroll to the top of the page and&nbsp;<strong>Skip</strong> the rest of the quick start guide. You will be taken back to your app&#39;s dashboard. Copy the App ID and paste it into the&nbsp;<strong>Facebook API ID&nbsp;</strong>in your Tumblr blog&#39;s customization settings.<br />
<br />
After this, your Facebook commenting plugin should be functional.
