+## Url Parameters
+
+Renkan accepts few Hash parameters allowing you to change the view, navigate in the map, highlight some nodes, etc. (e.g: http://myrenkan.com/renkan1/#?viewIndex=2&idNode=12345)
+Here is an exhaustive list of these parameters:
+* viewIndex=index: init the renkan with the indexed view. Negative index starts from the end of the list of views (viewIndex=-1 will load the last view). In case the view doesn't exist, the initial view (viewIndex=0) will be loaded.
+* view=offset-x,offset-y,zoom-level: Load a view with the given zoom and offset parameters
+* idNode=id: highlight a node according to the given node id.
