+## Component format
+
+A Dapr `conversation.yaml` component file has the following structure:
+
+```yaml
+apiVersion: dapr.io/v1alpha1
+kind: Component
+metadata:
+  name: ollama
+spec:
+  type: conversation.ollama
+  metadata:
+  - name: model
+    value: llama3.2:latest
+  - name: cacheTTL
+    value: 10m
+```
+
+{{% alert title="Warning" color="warning" %}}
+The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets, as described [here]({{< ref component-secrets.md >}}).
+{{% /alert %}}
+
+## Spec metadata fields
+
+| Field              | Required | Details | Example |
+|--------------------|:--------:|---------|---------|
+| `model` | N | The Ollama LLM to use. Defaults to `llama3.2:latest`.  | `phi4:latest` |
+| `cacheTTL` | N | A time-to-live value for a prompt cache to expire. Uses Golang duration format.  | `10m` |
