        Introduction
      </h1>
      <p>
        VROOM (short for <strong>V</strong>ideo <strong>ROOM</strong>) is a simple to use, web-based and opensource (MIT licence) video conferencing application.
      </p>
      <p>
        VROOM uses the latest WebRTC technologies to allow video conferencing through a web browser without any plugin.
        There are several more or less similar hosted solutions available (like
          <a href="https://talky.io/" target="_blank">talky.io</a>,
          <a href="https://appear.in/" target="_blank">appear.in</a>,
          <a href="https://vline.com/" target="_blank">vLine.com</a> for example).
        Most of them are more polished than VROOM, but I've found none entirely opensource, so I started this project.
      </p>
      <p>
        You can get the source, and follow the development of VROOM on the <a href="https://github.com/dani/vroom" target="_blank">github page</a>
        of the project.
      </p>



      <h1 id="features">
        Features
      </h1>
      <p>
        VROOM implements the following features:
        <ul>
          <li>Audio/Video conversations (no limit on the number of peers per room)</li>
          <li>Text chat (with possibility to save the history)</li>
          <li>Screen or single windows sharing sharing</li>
          <li>Invite anyone by email</li>
          <li>Be notified (by email) when someone joins one of your rooms</li>
          <li>Persistent/reserved rooms</li>
          <li>Chairman functionnalities (mute/pause/kick other peers)</li>
          <li>Grant chairman role to other peers</li>
          <li>Password protected rooms (different passwords for access and chairman)</li>
          <li>Music on hold (when you're alone in a room)</li>
          <li>Can be optionaly integrated with <a href="https://github.com/ether/etherpad-lite" target="_blank">Etherpad-Lite</a></li>
        </ul>
      </p>
      <p>
        VROOM is available in French and English. You're welcome to submit patches or pull requests to enhance existing localizations, or add new ones.
      </p>


      <h1 id="how_it_works">
        How it works
      </h1>
      <p>
        WebRTC allows browsers to browsers direct connections. This provides the best latency as it avoids round trip through a server,
        which is important with real time communications. But it also ensures the privacy of your communications. VROOM takes advantage of those
        new technologies, and does the following:
        <ul>
          <li>When a client joins a room, it establishes a <a href="https://en.wikipedia.org/wiki/WebSocket" target="_blank">websocket</a> connection to VROOM server. 
              This is called the signaling channel. With this, all peers are able to exchange small messages with each other. But messages sent through this channels are 
              routed through VROOM server, so it's not yet peer to peer</li>
          <li>When a second peer joins the same room, he gets informations about how to connect directly to the other one(s) through this signaling channel.</li>
          <li>Now, both peer exchange their video and audio stream directly</li>
          <li>The signaling channel stays open and is used to transmit non sensitive informations (peer colors synchronization, notification of muting/kicking etc...)</li>
          <li>Everything else (audio/video/text chat) is sent through data channels</li>
        </ul>
      </p>
      <div class="alert alert-warning">
        As long as possible, data channels and audio/video streams are established directly between peers, but in some situations, this is not possible (NAT, firewalls etc...). In those cases
        data streams are relayed through a <a href="https://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT" target="_blank">TURN</a> server
      </div>

      <h1 id="install_your_own">
        Install your own VROOM instance
      </h1>
      The following guide will help you installing VROOM on your own server

      <h2 id="requirements">
        Requirements
      </h2>
      <p>
        If you want to run your own VROOM instance, you'll need the following components
        <ul>
          <li><a href="http://mojolicio.us" target="_blank">Mojolicious</a> 5 or better</li>
          <li>A MySQL compatible server (MySQL or MariaDB)</li>
          <li>A webserver supporting HTTPS and reverse proxying, including websocket reverse proxying (Apache can do this with mod_proxy_wstunnel)</li>
          <li>The following perl modules
            <ul>
              <li>Mojolicious::Plugin::Mail</li>
              <li>Mojolicious::Plugin::Database</li>
              <li>Mojolicious::Plugin::StaticCompressor</li>
              <li>Crypt::SaltedHash</li>
              <li>MIME::Base64</li>
              <li>Etherpad::API</li>
              <li>Session::Token</li>
              <li>Config::Simple</li>
              <li>Email::Valid</li>
              <li>Protocol::SocketIO::Handshake</li>
              <li>Protocol::SocketIO::Message</li>
              <li>Data::Dumper</li>
              <li>DateTime</li>
            </ul>
          </ul>
        </ul>
        It's also advised to run VROOM on a systemd powered distribution (simply because that's what I use and I include service units for VROOM). 
        For the same reason, I recommend running Apache as webserver (others like Nginx probably work too, but I provide configuration sample only for Apache)
      </p>
      <div class="alert alert-warning">
        VROOM can probably work with other DB engine (like PostgreSQL) with minor modifications.
        If you're interrested in adding support for other engines, you're welcome to help
      </div>
      <div class="alert alert-warning">
        While VROOM should run on any distro, it's only tested on CentOS 7 x86_64, so it's the recommended platform.
        Also, all dependencies are available as RPM in <a href="http://repo.firewall-services.com/centos/" target="_blank">Firewall Services'</a> 
        repository, so installation will be easier on CentOS 7. 
        If you have it running on another system, please send me your notes so I can update this documentation.

        Two sample apache configurations are provided in the <strong>conf</strong> directory
        <ul>
          <li><strong>httpd_alias.conf</strong> should work out of the box, VROOM will be available at <em>https://yourservername/vroom</em></li>
          <li><strong>httpd_vhost.conf</strong> is an alternative which you can use if you prefer working with named virtualhosts 
              (but will require additional config adjustments, especially in ssl.conf, which is out of scope for this guide)</li>
        </ul>

        but you can change this to anything you want
      </div>
      <p>
        You also have to make sure the <strong>mod_proxy_wstunnel</strong> module is enabled, which is not the case by default on CentOS 7

cp /opt/vroom/conf/settings.ini.dist /opt/vroom/conf/settings.ini</pre>
        And edit it to your need. settings.ini has plenty of comments, but here's an explanation of the different sections and settings
      </p>

      <h3 id="settings_database">
       database
      </h3>
      <p>
        This section is where you define access to the database used by VROOM. The following settings are available
        <ul>
          <li><strong>dsn</strong>: The <strong>D</strong>ata <strong>S</strong>ource <strong>N</strong>ame for your database.
              For example <kbd>dsn = 'DBI:mysql:database=vroom;host=localhost'</kbd>. See perl DBI documentation if you want more information</li>
          <li><strong>user</strong>: This is the username for your database</li>
          <li><strong>password</strong>: The password for your database</li>
        </ul>
      </p>

      <h3 id="settings_turn">
       turn
      </h3>
      <p>
        This section defines which <a href="http://en.wikipedia.org/wiki/STUN" target="_blank">STUN</a> and 
        <a href="http://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT" target="_blank">TURN</a> servers
        will be used by the <a href="http://en.wikipedia.org/wiki/Interactive_Connectivity_Establishment" target="_blank">ICE</a> process. 
        If you plan to use VROOM only on a local network, where each peer can connect to each others, you can just omit this part. But if you want
        VROOM to work from anywhere, you'll need to use STUN and most likely TURN too.
        <ul>
          <li><strong>stun_server</strong>: The STUN server(s) to use. For example
            <kbd>stun_server = 'stun:stun.l.google.com:19302','stun:vroom.example.net:3478'</kbd>. 
          This must be a comma separated list of full STUN URI as defined by <a href="https://tools.ietf.org/html/rfc7064" target="_blank">rfc7064</a></li>

          <li><strong>turn_server</strong>: The TURN server(s) to use. For example
            <kbd>turn_server = 'turns:vroom.example.net:5349','turns:vroom.example.net:5349?transport=tcp'</kbd>.
          This must be a comma separated list of full STUN URI as defined by <a href="https://tools.ietf.org/html/rfc7065" target="_blank">rfc7065</a></li>

          <li><strong>credentials</strong>: This defines what TURN credentials are sent to clients. It can take two values:
            <ul>
              <li><strong>static</strong>: With this mode, you're using a single set of credentials (set with <strong>turn_user</strong> and
                <strong>turn_password</strong>) and they will be used by every peer in every room</li>
              <li><strong>rest</strong>: In this mode, VROOM will generate <a href="https://tools.ietf.org/html/draft-uberti-rtcweb-turn-rest-00" target="_blank">TURN REST API</a>
                compatible credentials for each room. Each credentials set will be valid only for 5 minutes. You must set <strong>secret_key</strong> to the same secret key
                set in your TURN server</li>
            </ul>
          </li>

          <li><strong>turn_user</strong> and <strong>turn_password</strong>: To use your TURN server, you'll most likely require credentials.
            If using static credentials, you must set this to the username and password the clients will use</li>

          <li><strong>secret_key</strong>: When using the <strong>rest</strong> credentials method, set this to the secret key shared with the turn server</li>          
        </ul>
      </p>

      <h3 id="settings_video">
        video
      </h3>
      <p>
        This section is for video quality settings. the available settings are
        <ul>
          <li><strong>frame_rate</strong>: Number of frames per second for webcam streams. A bigger number will provide a better quality stream
          but will also require more bandwidth and CPU on each peer. The default is 15 fps
        </ul>
      </p>

      <h3 id="settings_email">
        email
      </h3>
      <p>
        This section is for emails sent by VROOM (invitations, notifications, feedback form etc...). The available settings are
        <ul>
          <li><strong>from</strong>: The address used in the From field of emails sent by VROOM.</li>
          <li><strong>contact</strong>: The email address which will get feedback form submissions.</li>
          <li><strong>sendmail</strong>: The path to the sendmail compatible binary to use (default is /usr/bin/sendmail and will probably won't need to be changed)</li>
        </ul>
      </p>

      <h3 id="settings_interface">
        interface
      </h3>
      <p>
        This section controls the web interface. The available settings are
        <ul>
          <li><strong>powered_by</strong>: will be displayed in the footer. You can put HTML code here.</li>
          <li><strong>template</strong>: The name of the template to use. Must be a directory under <strong>templates</strong>. The default, 
          and only template provided is called <strong>default</strong>. But you can copy it and customize it to your needs</li>
          <li><strong>chrome_extension_id</strong>: This is the ID of the Chrome extension proposed to clients when trying to share screen for the first time
          (obviously, only for Chrome users). The reason this is configurable is because the extension requires the allowed websites to be listed.
          Two extensions are provided, the default (ecicdpoejfllflombfanbhfpgcimjddn) will work everywhere but allows screen capture on any website,
          which can be a security risk. The other extension (lfkdfilifapafomlhaaihfdglamkmdme) only works on <a href="https://vroom.im" target="_blank">https://vroom.im</a>.
          You can create your own extension which will only work for your site, and submit it to Google Chrome Store if you want.</li>
          <li><strong>demo</strong>: If enabled, a few more pages and elements will be displayed, like the documentation you're reading right now.</li>
        </ul>
      </p>


      <h3 id="settings_rooms">
        rooms
      </h3>
      <p>
        This section controls rooms behavior. The available settings are
        <ul>
          <li><strong>inactivity_timeout</strong>: The time (in minutes) after which a room without activity will be deleted</li>
          <li><strong>reserved_inactivity_timeout</strong>: The same, but for rooms which have been reserved (owner password set).
            You can set it to 0 if you do not want reserved room to expire</li>
          <li><strong>common_names</strong>: a comma separated list of names you don't want anyone to be able to reserve. Rooms with
            those names can be created, but not reserved. This is to prevent cybersquatting</li>
          <li><strong>max_members</strong>: This is the maximum number of peers able to be in a room at the same time. You can define a limit
            per room if you want. But the limit set here cannot be exceeded.</li>
        </ul>
      </p>


      <h3 id="settings_ertherpad">
        etherpad
      </h3>
      <p>
        Controls <a href="https://github.com/ether/etherpad-lite" target="_blank">Etherpad-Lite</a> integration. The following settings are available
        <ul>
          <li><strong>uri</strong>: The URI to reach your Etherpad Lite instance. This instance must share the same base domain as VROOM because
            of the way sessions are created (Etherpad Lite sessions are created by VROOM directly and sent as a cookie to the clients)</li>
          <li><strong>api_key</strong>: The API key of your Etherpad-Lite instance. You can find it in the file <strong>APIKEY.txt</strong> at the root
            of your Etherpad Lite installation</li>
          <li><strong>base_domain</strong>: This is the common part of your domain between VROOM and Etherpad-Lite. For example, if you have VROOM running
            on https://vroom.example.net/ and Etherpad-Lite as https://pads.example.net, you'd put <kbd>base_domain = 'example.net'</kbd> here</li>
        </ul>
      </p>

      <h3 id="settings_directories">
        directories
      </h3>
      <p>
        Controls where to find some specific directories
        <ul>
          <li><strong>cache</strong>: This is where VROOM will store its cache (including auto generated and compressed assets like JS and CSS bundles)</li>
        </ul>
      </p>

      <h3 id="settings_daemon">
        daemon
      </h3>
      <p>
        Controls how VROOM daemon behaves. The following settings are available
        <ul>
          <li><strong>listen_ip</strong>: This is the IP the daemon will listen on. Most of the time, you'll let <strong>127.0.0.1</strong> here as VROOM will
            be accessed through a reverse proxy</li>
          <li><strong>listen_port</strong>: The port VROOM daemon will bind to. Default is <strong>8090</strong>. Just be sure to adjust your reverse proxy
            configuration if you change this.</li>
          <li><strong>backend</strong>: The backend used to run VROOM. Can be either
