+### Using Workflow Summary
+
+You can automatically include the stale repository report in your GitHub Actions workflow summary by setting `WORKFLOW_SUMMARY_ENABLED: true`. This eliminates the need for additional steps to display the results.
+
+```yaml
+name: stale repo identifier
+
+on:
+  workflow_dispatch:
+  schedule:
+    - cron: "3 2 1 * *"
+
+permissions:
+  contents: read
+
+jobs:
+  build:
+    name: stale repo identifier
+    runs-on: ubuntu-latest
+
+    steps:
+      - name: Run stale_repos tool
+        uses: github/stale-repos@v3
+        env:
+          GH_TOKEN: ${{ secrets.GH_TOKEN }}
+          ORGANIZATION: ${{ secrets.ORGANIZATION }}
+          EXEMPT_TOPICS: "keep,template"
+          INACTIVE_DAYS: 365
+          ADDITIONAL_METRICS: "release,pr"
+          WORKFLOW_SUMMARY_ENABLED: true
+```
+
+When `WORKFLOW_SUMMARY_ENABLED` is set to `true`, the stale repository report will be automatically added to the GitHub Actions workflow summary, making it easy to see the results directly in the workflow run page.
