Nginx - Do I really need sites-available and sites-enabled folders? : <p>I have searched Stack Overflow for a straight answer but have not found it. I noticed my install of nginx has three folders called</p>

<pre><code>etc/nginx/sites-available
etc/nginx/sites-enabled
etc/nginx/conf.d
</code></pre>

<p>Do I really need these if I just want to work directly in the <code>etc/nginx/nginx.conf</code> file and remove the <code>include</code> lines that include these items in <code>nginx.conf</code>? Are these directories used for anything else that would mess things up if I delete them?</p>
