# Navigation service

Part of **Project Yukart**, making an old 2008 Mitsubishi Z27AG a bit smarter with modern technologies.  
This file serves as the minimalist portal to other docs


## What this repo is about

Runs on the Orin. Answers routing questions and publishes turn-by-turn guidance
onto the message bus, so no display has to know where routes come from.

Routing is served by a local Valhalla instance against artifacts built by
[tool-mapmint](gitea:yukart/tool-mapmint), which is the offline-capable default.
The provider is kept behind an interface so a cloud routing API can be swapped in
without touching anything downstream.
