          ### Verify Integrity

          ```bash
          # Download checksums
          curl -O https://github.com/syntaxis/syntaxis/releases/download/${{ needs.prepare.outputs.tag }}/SHA256SUMS

          # Verify bundles
          sha256sum -c SHA256SUMS
          ```

          ## What's Included
