    <p>Anaconda Repository will load configuration files with the extension <code class="docutils literal"><span class="pre">.yaml</span></code>

    <ul class="simple">
    <li><code class="docutils literal"><span class="pre">/etc/binstar/</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>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-default"><div class="highlight"><pre><span></span><span class="n">VALUE_ONE</span><span class="p">:</span> <span class="mi">50</span>
    </pre></div>
    </div>
    <p>Or you can set a value named VALUE_ONE to 50 with this command:</p>
