+### Using a Prompt File
+
+You can also provide a prompt file instead of an inline prompt:
+
+```yaml
+steps:
+  - name: Checkout repository
+    uses: actions/checkout@v4
+
+  - name: Run AI Inference with Prompt File
+    id: inference
+    uses: actions/ai-inference@v1
+    with:
+      prompt-file: './path/to/prompt.txt'
+
+  - name: Use Response File
+    run: |
+      echo "Response saved to: ${{ steps.inference.outputs.response-path }}"
+      cat "${{ steps.inference.outputs.response-path }}"
+```
+
+This is particularly useful for longer prompts or when you need to use the file
+path where the response is stored.
