+<h3>Summary</h3>
+
+        <p>
+        This module manages common properties of domains for one or more virtual hosts. 
+        Specifically it can use the ACME protocol
+        (<a href="https://datatracker.ietf.org/doc/draft-ietf-acme-acme/">RFC Draft</a>) 
+        to automate certificate provisioning. These will be configured for managed domains and
+        their virtual hosts automatically. This includes renewal of certificates before they
+        expire. The most famous Certificate Authority currently implementing the ACME protocol
+        is <a href="https://letsencrypt.org/">Let's Encrypt</a>.</p>
+        
+        <div class="warning"><h3>Warning</h3>
+            <p>This module is experimental. Its behaviors, directives, and 
+                defaults are subject to more change from release to 
+                release relative to other standard modules. Users are encouraged to 
+                consult the "CHANGES" file for potential updates.</p>
+        </div>
+
+        <p>Simple configuration example:</p>
+        
+        <div class="note"><h3>TLS in a VirtualHost context</h3>
+        <pre class="prettyprint lang-config">MDomain example.org
+
+&lt;VirtualHost *:443&gt;
+    ServerName example.org
+    DocumentRoot htdocs/a
+
+    SSLEngine on
+    # no certificates specification
+&lt;/VirtualHost&gt;</pre>
+
+        <p>
+            This setup will, on server start, contact
+            <a href="https://letsencrypt.org/">Let's Encrypt</a>
+            to request a certificate for the domain. If Let's Encrypt can verify the ownership
+            of the domain, the module will retrieve the certificate and its chain, store it
+            in the local file system (see <code class="directive"><a href="#mdstoredir">MDStoreDir</a></code>)
+            and provide it, on next restart, to mod_ssl.
+        </p><p>
+            This happens while the server is already running. All other hosts will continue
+            to work as before. While a certificate is not available, requests for the managed
+            domain will be answered with a '503 Service Unavailable'. 
+        </p>
+        </div>
+
+        <div class="note"><h3>Prerequisites</h3>
+        <p>
+            This module requires <code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code> to be loaded as well.
+        </p><p>
+            Certificate signup and renewal with Let's Encrypt requires your server to be
+            reachable on port 80 (http:) from the outside. The alternative method over
+            port 443 (https:) is currently disabled for security reasons (status from
+            2018-01-14).
+        </p><p>
+            The module will select from the methods offered by Let's Encrypt. If LE decides
+            at one point in the future, to re-enable it again, <code class="module"><a href="../mod/mod_md.html">mod_md</a></code> will
+            use it when suitable.
+        </p><p>
+            But for now, only the port 80 variant is available (termed "http-01"). Only
+            when LE can reach your server on port 80 will <code class="module"><a href="../mod/mod_md.html">mod_md</a></code> work for
+            you. For now, at least.
+        </p><p>
+            If you do not want to offer any sites on port 80 any more, you may leave it open
+            and redirect all requests to your https: sites instead. Use the
+            <code class="directive"><a href="#mdrequirehttps">MDRequireHttps</a></code> described below to do
+            that in a convenient fashion. This will continue to answer http: challenges
+            from Let's Encrypt. 
+        </p>

+                Defines what kind of private keys are generated for a managed domain and with
+                what parameters. The only supported type right now is 'RSA' and the only parameter
+                it takes is the number of bits used for the key.
+            </p><p>
+                The current (2017) recommendation is at least 2048 bits and a smaller number is
+                not accepted here. Higher numbers offer longer security, but are computationally more 
+                expensive, e.g. increase the load on your server. That might or might not be an
+                issue for you.

+            </p><p>
+                <strong>The following has consequences: </strong>if you want client to <strong>no longer</strong> use the
+             http: URLs, configure:
+            </p>
+            <div class="example"><h3>Permanent (for at least half a year!)</h3><pre class="prettyprint lang-config">MDRequireHttps permanent</pre>
+</div>
+            <p>This does two things:
+            </p>
+            <ol>
+                <li>All request to the <code>http:</code> resources are redirected to the
+                    same url with the <code>https:</code> scheme using the <code>301</code>
+                status code. This tells clients that this is intended to be forever and
+                the should update any links they have accordingly.
+                </li>
+                <li>All answers to <code>https:</code> requests will carry the header
+                    <code>Strict-Transport-Security</code> with a life time of half a year.
+                    This tells the browser that it <strong>never</strong> (for half a year) shall use <code>http:</code>
+                    when talking to this domain name. Browsers will, after having seen this, refuse
+                    to contact your unencrypted site. This prevents malicious middleware to
+                    downgrade connections and listen/manipulate the traffic. Which is good. But
+                    you cannot simply take it back again.
+                </li>
+            </ol>
+            <p>You can achieve the same with mod_alias and some Redirect configuration,
+            basically. If you do it yourself, please make sure to exclude the paths 
+            /.well-known/* from your redirection, otherwise mod_md might have trouble 
+            signing on new certificates.
