title: How to Add a Geocoding Service as a Form of Plugin (For Leaflet)
body: <p>I am specifically using Leaflet Routing Machine plugin and I have been trying to add a geocoding service to the plugin but I have been facing some difficulties. I tried Bing, Google and Nominatim but I'm unable to load any of the geocoding service successfully. </p>
  
  <p>Would anyone be kind enough to help me on this? I hope to add the geocoding service for free. Thank you! </p>
