 106 <h2 id="foreword">Foreword</h2>
 107 <p><strong>Do not edit configuration options in index.php! Your changes would be lost.</strong></p>
 108 <p>Once your Shaarli instance is installed, the file <code>data/config.php</code> is generated:</p>
 109 <ul>
 110 <li>it contains all settings, and can be edited to customize values</li>
 111 <li>it defines which <a href="Plugin-System">plugins</a> are enabled<a href=".html"></a></li>
 112 <li>its values override those defined in <code>index.php</code></li>
 113 </ul>
 114 <h2 id="file-and-directory-permissions">File and directory permissions</h2>
 115 <p>The server process running Shaarli must have:</p>
 116 <ul>
 117 <li><code>read</code> access to the following resources:
 118 <ul>
 119 <li>PHP scripts: <code>index.php</code>, <code>application/*.php</code>, <code>plugins/*.php</code></li>
 120 <li>3rd party PHP and Javascript libraries: <code>inc/*.php</code>, <code>inc/*.js</code></li>
 121 <li>static assets:
 122 <ul>
 123 <li>CSS stylesheets: <code>inc/*.css</code></li>
 124 <li><code>images/*</code></li>
 125 </ul></li>
 126 <li>RainTPL templates: <code>tpl/*.html</code></li>
 127 </ul></li>
 128 <li><code>read</code>, <code>write</code> and <code>execution</code> access to the following directories:
 129 <ul>
 130 <li><code>cache</code> - thumbnail cache</li>
 131 <li><code>data</code> - link data store, configuration options</li>
 132 <li><code>pagecache</code> - Atom/RSS feed cache</li>
 133 <li><code>tmp</code> - RainTPL page cache</li>
 134 </ul></li>
 135 </ul>
 136 <p>On a Linux distribution:</p>
 137 <ul>
 138 <li>the web server user will likely be <code>www</code> or <code>http</code> (for Apache2)</li>
 139 <li>it will be a member of a group of the same name: <code>www:www</code>, <code>http:http</code></li>
 140 <li>to give it access to Shaarli, either:
 141 <ul>
 142 <li>unzip Shaarli in the default web server location (usually <code>/var/www/</code>) and set the web server user as the owner</li>
 143 <li>put users in the same group as the web server, and set the appropriate access rights</li>
 144 </ul></li>
 145 <li>if you have a domain / subdomain to serve Shaarli, <a href="Server-configuration">configure the server</a> accordingly<a href=".html"></a></li>
