-<div id="instructions">
-  <p>This page assists in the installation and configuration of <a href="http://wiki.splitbrain.org">Dokuwiki</a>.</p>
-  <p>Dokuwiki uses ordinary files for the storage of wiki pages and other information associated with those pages 
-  (e.g. images, search indexes, old revisions, etc).  In order to operate successfully Dokuwiki <strong>must</strong>
-  have write access to the directories that hold those files.  This installer is not capable of setting up directory 
-  permissions, that normally needs to be done directly or if you are using hosting, through your hosting 
-  control panel (e.g. cPanel).</p>
-  <p>This installer will setup your Dokuwiki configuration for <span class="abbr" title="access control list">ACL</span>, 
-  which in turn allows administrator login and access to Dokuwiki's admin menu for installing plugins, managing 
-  users, managing access to wiki pages and alteration of configuration settings.  It isn't required for Dokuwiki to 
-  operate, however it will make Dokuwiki easier to administer.</p>
-  <p>Use these links for details concerning <a href="http://wiki.splitbrain.org/wiki:installation">installation instructions</a>
-  and <a href="http://wiki.splitbrain.org/wiki:configuration">configuration settings</a>.</p>
