== Description ==
Add a gpx trak with altitude graph
WP-GPX-Maps
== Installation ==
This section describes how to install the plugin and get it working.
e.g.
1. Use the classic wordpress plugin installer or copy the plugins folder to the `/wp-content/plugins/` directory
1. Activate the plugin through the 'Plugins' menu in WordPress
1. Add the shortcode [sgpx gpx="<relative path to your gpx>"]
