-# OsmAnd routing.xml
+# OsmAnd routing.xml for Inline Skating
 
-Original version
+This file adds a new option to the bicycle mode
+to tweak the routing algorithm for inline skating:
+
+![Inline skates mode](inline-skates-mode.png)
+
+The basic principle is to avoid non-smooth surfaces by all means.
+Primary roads can be used, but the algorithm should look for
+nicer routes.
+
+It seems to work pretty well, however, beware of steep segments.
+
+Just copy the file to the OsmAnd folder.
+Also see a [Google Group discussion](https://groups.google.com/forum/#!topic/osmand/JmMQ0bQV68I).
+
+The original `routing.xml` [is on GitHub](https://github.com/osmandapp/OsmAnd-resources/blob/master/routing/routing.xml).
+
+## Uncertainties
+
+* OSM's [`tracktype`](http://wiki.openstreetmap.org/wiki/Key:tracktype)
+and [`smoothness`](http://wiki.openstreetmap.org/wiki/Key:smoothness)
+seem to be redundant somehow…
+* It seems to be impossible to add a completely new
+["application mode"](https://github.com/osmandapp/Osmand/blob/master/OsmAnd/src/net/osmand/plus/ApplicationMode.java)
+without programming.
