<p>If you need spell check features, create a file <code>data/hooks/phpfpm/aspell.sh</code> with the following content, then <code>chmod +x data/hooks/phpfpm/aspell.sh</code>.

<p>Download the latest release of <a href="https://github.com/mstilkerich/rcmcarddav">RCMCardDAV</a> to the Roundcube plugin directory and extract it (here <code>rc/plugins</code>):

</code></pre></div></p>
<p>Copy the file <code>config.inc.php.dist</code> to <code>config.inc.php</code> (here in <code>rc/plugins/carddav</code>) and append the following preset to the end of the file - don't forget to replace <code>mx.example.org</code> with your own hostname:

</code></pre></div>
Please note, that this preset only integrates the default addressbook (the one that's named "Personal Address Book" and can't be deleted). Additional addressbooks are currently not automatically detected but can be manually added within the roundecube settings.</p>
<p>Enable the plugin by adding <code>carddav</code> to <code>$config['plugins']</code> in <code>rc/config/config.inc.php</code>.</p>
<p>If you want to remove the default addressbooks (stored in the Roundcube database), so that only the CardDAV addressbooks are accessible, append <code>$config['address_book_type'] = '';</code> to the config file <code>data/web/rc/config/config.inc.php</code>.</p>
<hr />
<p>Optionally, you can add Roundcube's link to the mailcow Apps list.
To do this, open or create <code>data/web/inc/vars.local.inc.php</code> and add the following code-block:</p>
<p><em>NOTE: Don't forget to add the <code>&lt;?php</code> delimiter on the first line</em></p>
<div class="highlight"><pre><span></span><code>...
$MAILCOW_APPS = array(
