+# Optimizing Santa's Travels (Java Advent)
+
+This repository contains the example code for my blog post at [Java Advent](https://www.javaadvent.com/).
+It is purposefully kept simplistic to show how to use *Timefold Solver* in a minimal example.
+
+For more advanced examples, check out the [Timefold Quickstarts Repository](https://github.com/TimefoldAI/timefold-quickstarts).
+
+## Technologies Used
+
+- [Timefold Solver](https://docs.timefold.ai/timefold-solver/latest/introduction), an Open Source AI Solver.
+- [Quarkus](https://quarkus.io/), the Supersonic Subatomic Java Framework.
+- [LeafletJS](https://leafletjs.com/), Javascript library for interactive maps.
+
+## Running the application
+You can run your application in dev mode that enables live coding using:
+
+```shell script
+./mvnw compile quarkus:dev
+```
+
+After visiting localhost:8080, you will be presented with a simple UI.
+Click the map a couple of times to add some visits for Santa, then click the _solve_ button.
