+# Podinfo signed releases
+
+Podinfo release assets such as the Helm chart and the Flux artifact
+are published to GitHub Container Registry and are signed with
+[Notation](https://github.com/notaryproject/notation).
+
+## Generate signing keys
+
+Generate a new signing key pair:
+
+```sh
+openssl genrsa -out podinfo.key 2048
+openssl req -new -key podinfo.key -out podinfo.csr -config codesign.cnf
+openssl x509 -req -days 1826 -in podinfo.csr -signkey podinfo.key -out notation.crt -extensions v3_req -extfile codesign.cnf
