 1. Set `global.imageRegistry`, `global.imageNamespace`, and `global.imageTag` so the chart pulls the images published by the Gitea workflow.
 2. Set `web.config.apiUrl` and `web.config.wsUrl` to browser-reachable endpoints before exposing the web UI.
 3. The shared `packs`, `runtime_envs`, and `artifacts` PVCs default to `ReadWriteMany`; your cluster storage class must support RWX or you need to override those claims.

+Each agent worker uses an init container to copy the statically-linked
+attune-agent binary into the worker pod via an emptyDir volume. The agent
+auto-detects available runtimes in the container and registers with Attune.
+
+The default sensor deployment also uses the same injection pattern, copying
+`attune-sensor-agent` into the pod before starting a stock runtime image.
+
+To add more agent workers, append entries to `agentWorkers` in your values:
