+## Reports
+
+Set `report: true` to generate a human-readable maturity report — the overall
+score and level, a per-category breakdown, and the list of unmet criteria with
+improvement recommendations. The report is written to the workflow run's
+[job summary](https://docs.github.com/actions/using-workflows/workflow-commands-for-github-actions#adding-a-job-summary),
+so it shows up directly on the Actions run page — no artifact download needed.
+
+```yaml
+- uses: devops-maturity/devops-maturity-action@v1
+  with:
+    github-token: ${{ secrets.GITHUB_TOKEN }}
+    report: true
+```
+
+The same Markdown is also written to a file, exposed via the `report-path`
+output, so you can upload it as an artifact if you want to keep it:
+
+```yaml
+- id: maturity
+  uses: devops-maturity/devops-maturity-action@v1
+  with:
+    github-token: ${{ secrets.GITHUB_TOKEN }}
+    report: true
+
+- uses: actions/upload-artifact@v4
+  with:
+    name: devops-maturity-report
+    path: ${{ steps.maturity.outputs.report-path }}
+```
