+        If you want to integrate VROOM with Etherpad-Lite, you'll have to get your instance running. First, install the dependencies
+        <pre>
+yum groupinstall "Development Tools"</pre>
+        Then, Create a user, clone the repository and prepare the config
+        <pre>
+useradd etherpad
+cd /opt
+git clone https://github.com/ether/etherpad-lite.git
+chown -R etherpad:etherpad ./etherpad-lite
+cp -a etherpad-lite/settings.json.template etherpad-lite/settings.json</pre>
+      </p>
+      <div class="alert alert-info">
+        Adapt /opt/etherpad-lite/settings.json to your need. The important settings are
+        <ul>
