 ## Usage
 
 ### Preparing the file
 
 You first need to have a trace file in *gpx* format.
 Usually I download from [komoot](https://www.komoot.com/) or I export

+from google maps using [mapstogpx](https://mapstogpx.com/). [Brouter](https://brouter.damsy.net) is
+also a nice open source option.
 
 Note that *mapstogpx* has a super nice feature in its advanced settings.
 You can turn on 'next turn info' and be warned by the watch when you need to turn.

 Note that while lost, the app will slow down a lot since it will start scanning all possible points to figure out where you
 are. On path it just needed to scan a few points ahead and behind.

 ### Settings
 
 Few settings for now (feel free to suggest me more) :
 
-- keep gps alive : if turned off, will try to save battery by turning the gps off on long segments
-- max speed : used to compute how long to turn the gps off
-- display points : display/hide points (not waypoints)
+- lost distance : at which distance from path are you considered to be lost ?
 
 ### Caveats
 
@@ -109,8 +108,8 @@ It is good to use but you should know :
 - the gps might take a long time to start initially (see the assisted gps update app).
 - gps signal is noisy : there is therefore a small delay for instant speed. sometimes you may jump somewhere else.
 - your gpx trace has been decimated and approximated : the **REAL PATH** might be **A FEW METERS AWAY**
-- sometimes the watch will tell you that you are lost but you are in fact on the path.
-- battery saving by turning off gps is not very well tested (disabled by default).
+- sometimes the watch will tell you that you are lost but you are in fact on the path. It usually figures again
+the real gps position after a few minutes. It usually happens when the signal is acquired very fast.
 - buzzing does not always work: when there is a high load on the watch, the buzzes might just never happen :-(.
 - buzzes are not strong enough to be always easily noticed.
 - be careful when **GOING DOWNHILL AT VERY HIGH SPEED**. I already missed a few turning points and by the time I realized it,
