+- Container images
+
+This ensures that the images you pull are authentic, tamper-proof, and built by the official Seerr release pipeline.
+
+Additionally each container image also includes a CycloneDX SBOM (Software Bill of Materials) attestation, generated with [Trivy](https://aquasecurity.github.io/trivy/), providing transparency about all dependencies included in the image.
