[gmw_single_location] Documentation??

Hi Firstly thanks for a really great plugin. In general it works very well.

I did struggle to find info on the [gmw_single_location] shortcode. Is there any shrotcode documentation anywhere which explains how to use this. The wp.org page and plugin site mentions the shortcode only briefly without specifying it’s syntax or if there’s any additional parameters and I can’t find anything within the plugin’s settings.

It may just be my own ignorance not being able to find the info.

Can anyone point m in the right direction?
