		<b>The fastest way to use this plugin:</b><br /> upload the file using the uploader in the first tab, than copy the shortcode from the list and paste it in the pages/posts.
		<p>You can manually set the relative path to your gpx: <b>[sgpx gpx="<?php echo $relativeGpxPath; ?>&lt gpx file name &gt"]</b>.</p>
		<p>You can also use gpx from other sites: <b>[sgpx gpx="http://www.someone.com/somewhere/somefile.gpx"]</b></p>
