 # Gipy
 
-Development still in progress. Follow compressed gpx traces.
+Gipy allows you to follow gpx traces on your watch.
-Will warn you before reaching intersections and try to turn off gps.
+
+It is meant for bicycling and not hiking
+(it uses your movement to figure out your orientation).
+
+It provides the following features :
+
+- display the path with current position from gps
+- detects and buzzes if you leave the path
+- buzzes before sharp turns
+- buzzes before nodes with comments
+(for example when you need to turn in https://mapstogpx.com/)
+- display instant / average speed
+- display distance to next node
+
+optionally it can also :
+
+- display additional data from openstreetmap :
+    - water points
+    - toilets
+    - artwork
+    - bakeries
+
+- try to turn off gps between crossroads to save battery
 
 ## Usage
 
-WIP.
+You first need to convert your .gpx file to a .gpc (our custom lightweight trace).
+Then launch gipy and select a trace to follow.
