+> How can I access the SBOM for flagd?
+
+SBOMs for the flagd binary are available as assets on the [GitHub release page](https://github.com/open-feature/flagd/releases).
+Container SBOMs can be inspected using the Docker CLI.
+
+An example of inspecting the SBOM for the latest flagd `linux/amd64` container image:
+
+```shell
+docker buildx imagetools inspect ghcr.io/open-feature/flagd:latest \
+    --format '{{ json (index .SBOM "linux/amd64").SPDX }}'
+```
+
+An example of inspecting the SBOM for the latest flagd `linux/arm64` container image:
+
+```shell
+docker buildx imagetools inspect ghcr.io/open-feature/flagd:latest \
+    --format '{{ json (index .SBOM "linux/arm64").SPDX }}'
+```
