 ## Roadmap
-- [ ] Implement the interface for a data source
-- [ ] Finish implementing BeamNG
+- [X] Implement the interface for a data source
 - [ ] Configuration of the peripherals via ESDI
 - [ ] Detection of the display
-- [ ] Fuel Calculator
 - [ ] LapTime Calculator
 - [ ] A very long list useful stuff like flags, position, more info about
 other drivers, track conditions and so on so forth
-- [ ] Dynamic data packets
-- [ ] More roadmap entries
 - [ ] Telemetry analysis tool
 - [ ] Better user interface

+## Development
+### Mockservers
+To mock [BeamNG.drive](https://www.beamng.com/game/), I built 
+[BeaMNGMockOg](https://github.com/ESilva15/BeamNGMockOg) (should have though longer
+about the name).
+You create a recording by launching the BeamNG and then launching the mockserver with:
+`BeamNGMockOg record -a 127.0.0.1 -p 4443 -o output.bin`.
+
+To replay the recording: 
+`BeamNGMockOg replay [--loop] -a 127.0.0.1 -p 4443 -i input.bin`
+
+### Troubleshooting
+#### Can't see BeamNG data coming through
+Use, for example, `tcpdump -i any udp port <port> -X` to check if any data is available.
+
+
