-This example shows how to verify a blob, using a bundle that was created by the
-`cosign sign-blob` command.
-
-### Create the artifact to be signed.
-```console
-cd examples/cosign/verify-bundle
-echo something > artifact.txt
-```
-
-### Sign the artifact.txt file using cosign
-```
-cosign sign-blob --bundle=artifact.bundle artifact.txt
-```
-
-### Verify using sigstore-rs:
-```console
-cargo run --example verify-bundle -- \
-    --rekor-pub-key ~/.sigstore/root/targets/rekor.pub \
-    --bundle artifact.bundle \
-    artifact.txt
-```
