    <p>Anaconda Repository will load configuration files with the extension <code class="docutils literal"><span class="pre">.yaml</span></code>
    from the following locations:</p>
    <ul class="simple">
    <li><code class="docutils literal"><span class="pre">/etc/binstar/</span></code></li>
    <li><code class="docutils literal"><span class="pre">/etc/anaconda-server/</span></code></li>
    <li><code class="docutils literal"><span class="pre">$PREFIX/etc/anaconda-server</span></code></li>
    </ul>
    <p><code class="docutils literal"><span class="pre">$PREFIX</span></code> is the location where Anaconda Repository was installed.</p>
    <p>Files are loaded from these directories in order, with later files overriding earlier
    files. Files are loaded from each directory in alphabetical order.</p>
    <p>If an environment variable ANACONDA_SERVER_CONFIG is set with the path of a
    configuration file, this file is loaded after the three already listed. Its
    settings will override any conflicting settings in the earlier files.</p>
    <p>Each configuration setting variable can have its value set with the
    <code class="docutils literal"><span class="pre">anaconda-server-config</span> <span class="pre">--set</span></code> command, or by editing a configuration file.</p>
    <p>For example, you can set a value named VALUE_ONE to 50 by adding this to a configuration file:</p>
    <div class="highlight-python"><div class="highlight"><pre><span></span>VALUE_ONE: 50
    </pre></div>
    </div>
    <p>Or you can set a value named VALUE_ONE to 50 with this command:</p>
    <div class="highlight-python"><div class="highlight"><pre><span></span>anaconda-server-config --set VALUE_ONE 50
    </pre></div>
