+# This workflow uses actions that are not certified by GitHub.
+# They are provided by a third-party and are governed by
+# separate terms of service, privacy policy, and support
+# documentation.
+#
+# The zimperium-zscan GitHub action scans your mobile app binary (iOS or Android)
+# and identifies security, privacy, and compliance-related vulnerabilities. ​
+#
+# Prerequisites:
+#  * An active Zimperium zScan account is required. If you are not an existing Zimperium
+#    zScan customer, please request a zSCAN demo by visiting https://www.zimperium.com/contact-us.
+#  * Either GitHub Advanced Security (GHAS) or a public repository is required to display
+#    issues and view the remediation information inside of GitHub code scanning alerts.​
+#
