+# Release Artifacts
+
+[See all the available artifacts](https://github.com/orgs/projectcapsule/packages?repo_name=cortex-proxy)
+
+## Verifing
+
+To verify artifacts you need to have [cosign installed](https://github.com/sigstore/cosign#installation). This guide assumes you are using v2.x of cosign. All of the signatures are created using [keyless signing](https://docs.sigstore.dev/verifying/verify/#keyless-verification-using-openid-connect).
+To verify the signature of the docker image, run the following command. Replace `<release_tag>` with an [available release tag](https://github.com/projectcapsule/cortex-proxy/pkgs/container/cortex-proxy). The value `release_tag` is a release but without the prefix `v` (eg. `0.1.0-alpha.3`).
+
+    VERSION=<release_tag> cosign verify ghcr.io/projectcapsule/cortex-proxy:${VERSION} \
+      --certificate-identity-regexp="https://github.com/projectcapsule/cortex-proxy/.github/workflows/docker-publish.yml@refs/tags/*" \
+      --certificate-oidc-issuer="https://token.actions.githubusercontent.com" | jq
+
+To verify the signature of the helm image, run the following command. Replace `<release_tag>` with an [available release tag](https://github.com/projectcapsule/cortex-proxy/pkgs/container/charts%2Fcortex-proxy). The value `release_tag` is a release but without the prefix `v` (eg. `0.1.0-alpha.3`)

+      --certificate-oidc-issuer="https://token.actions.githubusercontent.com" | jq
+
+## Verifying Provenance
+
+We create and attest the provenance of our builds using the [SLSA standard](https://slsa.dev/spec/v0.2/provenance) and meets the [SLSA Level 3](https://slsa.dev/spec/v0.1/levels) specification. The attested provenance may be verified using the cosign tool.
+
+Verify the provenance of the docker image. Replace `<release_tag>` with an [available release tag](https://github.com/projectcapsule/cortex-proxy/pkgs/container/cortex-proxy). The value `release_tag` is a release but without the prefix `v` (eg. `0.1.0-alpha.3`)
+
+```bash

+## Software Bill of Materials (SBOM)
+
+An SBOM (Software Bill of Materials) in CycloneDX JSON format is published for each release, including pre-releases.
+
