+## Helm Chart (Kubernetes)
+
+When deploying via the openab Helm chart, STT is a first-class config block — no manual configmap patching needed:
+
+```bash
+helm upgrade openab openab/openab \
+  --set agents.kiro.stt.enabled=true \
+  --set agents.kiro.stt.apiKey=gsk_xxx
+```
+
+The API key is stored in a K8s Secret and injected as an env var (never in plaintext in the configmap). You can also customize model and endpoint:
+
+```bash
+helm upgrade openab openab/openab \
+  --set agents.kiro.stt.enabled=true \
+  --set agents.kiro.stt.apiKey=gsk_xxx \
+  --set agents.kiro.stt.model=whisper-large-v3-turbo \
+  --set agents.kiro.stt.baseUrl=https://api.groq.com/openai/v1
+```
