            <p>The <code>"alt"</code> and <code>"tileUrl"</code> parameters are mandatory. <code>"tileUrl"</code> can contain {x}, {y} and {z} for Google-style coordinate systems (also works with TMS systems like Eniro, but needs the <code>"scheme":"tms"</code> parameter), or {q} for Bing-style quadkeys. GME can also connect with WMS servers, in which case a <code>"layers"</code> parameter is required.</p>\
