 ## How to access the logs

 To access the logs from all the containers use: `docker compose logs -f`.
 
 To access the logs of one specific container:
+
 - Caddy: `docker compose logs -f caddy`
 - SearXNG: `docker compose logs -f searxng`
-- Redis: `docker compose logs -f redis`
+- Valkey: `docker compose logs -f redis`
