 You can download Docker Compose binaries from the
 [release page](https://github.com/docker/compose/releases) on this repository.
 
+We generate [SLSA3 provenance](slsa.dev) using the OpenSSF's [slsa-framework/slsa-github-generator](https://github.com/slsa-framework/slsa-github-generator). To verify the binaries:
+1. Install the verification tool from [slsa-framework/slsa-verifier#installation](https://github.com/slsa-framework/slsa-verifier#installation)
+1. Download the file named `attestation.intoto.jsonl` from the release
+1. Run:
+```shell
+$ slsa-verifier -artifact-path <binary> -provenance attestation.intoto.jsonl -source github.com/docker/compose -branch v2
+  PASSED: Verified SLSA provenance
+```
+

 Rename the relevant binary for your OS to `docker-compose` and copy it to `$HOME/.docker/cli-plugins` 
 
 Or copy it into one of these folders for installing it system-wide:
