# 🛋️ Laterna (Server)

## 🏵️ Setup

Laterna requires a config.json in it's root directory. An [example config](https://github.com/siestaw/Laterna/blob/main/config.json.example) is provided

`$ mv config.json.example config.json`

You can leave the json as it is or configure it to your liking, although some configuration options (e.g. `verboseLogging`) aren't fully implemented yet.
