+### Quickstart Configuration
+
+In this tutorial we use a simplified configuration.  
+You can find it in `contrib/quickstart/5-min/hydra.yml`.  
+The configuration gets loaded in docker-compose as specified in the
+`quickstart.yml`.
+
+```yml
+serve:
+cookies:
+  same_site_mode: Lax
+  # cookies are only set when the domain in the URL of the browser matches the domain of the cookie
+
+urls:
+self:
+  issuer: http://127.0.0.1:4444
+consent: http://127.0.0.1:3000/consent
+login: http://127.0.0.1:3000/login
+logout: http://127.0.0.1:3000/logout
