 <p>The file contains parameters such as the player to use, the playlist to load etc. It is heavily commented (as you can see <a href="pyradio/config">here</a>), so that manual editing is really easy. The best practice to manually edit this file is executing <strong><em>PyRadio</em></strong> with the <strong>-ocd</strong> command line option, which will open the configuration directory in your file manager, and then edit it using your preferable text editor.</p>
