 Simple app to ease custom location sending to Xcode Simulator.
 
-![](./demo/demo.gif)
 
-**Core features:**
+📍 Send location by searching an address or clicking on map
+![](./demo/v2.0.0/search-demo.gif)
 
-• Search location by address
+🏁 Automate location sending by providing a GeoJSON
+![](./demo/v2.0.0/routing-demo.gif)
 
-• Click on map
+## A note on routing mode
 
-**Planned features (ETA, when it's done):**
+### Playback capabilities
 
-• Allow simulation of route, via .gpx import.
+- Play/Pause
+- Reset
+- Loop
+- Playback rate control (from 100ms to 5s)
+- Playback feedback on map (green part is what has been played)
 
-• Add support for modern app icon via [./src/LocationSenderForSimulator/Icon.icon](./src/LocationSenderForSimulator/Icon.icon) 
+### GeoJSON
+
+Routing mode relies on [GeoJSON](https://geojson.org) file. 
+
+This way you can provide your own route made of WGS84 coordinates. Your GeoJSON may contain the following objects :
+ 
+| Objects | Behavior |
+| - | - |
+| Linestring | Each point will be considered as part of the route | 
+| MultiPoint | Each point will be considered as part of a single line/route |
+| Polygon | Each point will be considered as part of a single line/route |
+| MultiLineString | Only first line will be considered as route |
+| MultiPolygon | Only first polygon will be considered as route |
+| Feature | Geometry will be considered if it matches one of the previous enumerated type |
+| FeatureCollection | First feature with a supported geometry type will be considered |
+
+_n.b as a result, every geometry made of less than two points are incompatible._
+
+You can find sample [GeoJSON](https://geojson.org) files [here](./samples/).
+
+Build your own via [geojson.io](https://geojson.io/)!
+
+## Considered features (ETA, when it's done)
+
+- Route playback based on speed instead of point rate
+- Add support for modern app icon via [./src/LocationSenderForSimulator/Icon.icon](./src/LocationSenderForSimulator/Icon.icon) 
 
 _n.b this app is not compatible with App Sandbox_
