 ## Creating attestations
 
-When you build an image with `docker buildx build`, you can add attestation
-records to the resulting image using the `--provenance` and `--sbom` options.
-You can opt in to add either the SBOM or provenance attestation type, or both.
-
-```console
-$ docker buildx build --sbom=true --provenance=true .
+BuildKit generates the attestations when building the image. Provenance
+attestations with the `mode=min` level are added to images by default. The
+attestation records are wrapped in the in-toto JSON format and attached to the
+image index in a manifest for the final image.
+
+You can customize attestation behavior using the `--provenance` and `--sbom`
+flags:
+
+```bash
+# Opt in to SBOM attestations:
+docker buildx build --sbom=true .
+# Opt in to max-level provenance attestations:
+docker buildx build --provenance=mode=max .
+# Opt out of provenance attestations:
+docker buildx build --provenance=false .

-> To make sure the attestations are preserved, you can:

-> - Enable the [containerd image store](/manuals/desktop/features/containerd.md).
-
-> [!NOTE]
->
-> Provenance attestations are enabled by default, with the `mode=min` option.
-> You can disable provenance attestations using the `--provenance=false` flag,
