+## Server runtime profiles
+
+Serve mode enables named runtime profiles by default. A client can send
+`config.model_name="custodian-triage-balanced"` and the server resolves it to
+the configured provider/model before calling the adapter.
+
+Useful runtime environment variables:
+
+```bash
+LLM_CONNECT_HOST=0.0.0.0
+LLM_CONNECT_PORT=8080
+LLM_CONNECT_PROVIDER=openrouter
+LLM_CONNECT_MODEL=anthropic/claude-sonnet-4
+LLM_CONNECT_CUSTODIAN_TRIAGE_PROVIDER=openrouter
+LLM_CONNECT_CUSTODIAN_TRIAGE_MODEL=anthropic/claude-sonnet-4
+```
+
+For local smoke tests without provider credentials:
+
+```bash
+export LLM_CONNECT_MOCK_RESPONSE="$(python -c 'import json; print(json.dumps(json.load(open("fixtures/activity_core/daily-triage-valid-content.json"))))')"
+python -m llm_connect.server --provider mock
+python scripts/smoke_activity_core_endpoint.py --url http://127.0.0.1:8080
+```
+
+Disable profile dispatch with `--disable-profiles`. Set
+`LLM_CONNECT_STRICT_PROFILES=1` or pass `--strict-profiles` to reject direct
+model names that are not configured profiles.
+
+## Writing your own adapter
 
 ```python
 from llm_connect import LLMAdapter, RunConfig, LLMResponse
