+#### Background worker note
+
+The Docker Compose stack starts a dedicated worker container by default. If `REDIS_URL` is not configured, the worker will start, log that it is idle, and do no queue processing. This is expected. Queue-backed API, webhook, and schedule execution requires Redis; installs without Redis continue to use the inline execution path.
+
 Sim also supports local models via [Ollama](https://ollama.ai) and [vLLM](https://docs.vllm.ai/) — see the [Docker self-hosting docs](https://docs.sim.ai/self-hosting/docker) for setup details.
