### navd
`navd` takes in a route through the `NavDestination` param and sends out two packets: `navRoute` and `navInstruction`. These packets contain the coordinates of the planned route and turn-by-turn instructions.

## development
Currently, [mapbox](https://www.mapbox.com/) is used for navigation.
* get an API token: https://docs.mapbox.com/help/glossary/access-token/
* set an API token using the `MAPBOX_TOKEN` environment variable
* routes/destinations are set through the `NavDestination` param
* use `set_destination.py` for debugging
* edit the map: https://www.mapbox.com/contribute
* mapbox API playground: https://docs.mapbox.com/playground/
