 ## Getting Started
 
 You can get started with Tinyauth by following the guide in the [documentation](https://tinyauth.app/docs/getting-started). There is also an available [docker-compose](./docker-compose.example.yml) file that has Traefik, Whoami and Tinyauth to demonstrate its capabilities (keep in mind that this file lives in the development branch so it may have updates that are not yet released).
