+Miroir has been installed!

+Then visit http://localhost:7700/health to verify the proxy is running.
+
+Components deployed:

+  - Meilisearch ({{ .Values.meilisearch.replicas }} node(s))

+
+!!! PRODUCTION UPGRADE PATH !!!
+These defaults are for dev/CI (single-pod evaluation). For production, override:
+  miroir.replicas=2+
+  miroir.replicationFactor=2
+  miroir.replicaGroups=2
+  taskStore.backend=redis
