                 If you check the encryption box, communication between browser and WeeChat will be encrypted.<br>
                 <strong>Note</strong>: Due to a <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=594502">bug</a> encryption will not work in Firefox. You must also first visit the URL https://weechathost:relayport/ to accept the certificate</p>
                 If you want to use encrypted session you first have to set up the relay using SSL like this:
-                <pre>
-          $ mkdir -p ~/.weechat/ssl
-          $ cd ~/.weechat/ssl
-          $ openssl req -nodes -newkey rsa:2048 -keyout relay.pem -x509 -days 365 -out relay.pem
-          </pre>
+<pre>
+$ mkdir -p ~/.weechat/ssl
+$ cd ~/.weechat/ssl
+$ openssl req -nodes -newkey rsa:2048 -keyout relay.pem -x509 -days 365 -out relay.pem
+</pre>
                 If WeeChat is already running, you can reload the certificate and private key with command:
-                <pre>
-          /relay sslcertkey
-          /relay add ssl.weechat 8000
-          </pre>

+/relay sslcertkey
