+
+Notes:
+  Mondoo needs a personal access token to scan a GitHub organization, public repo, or private repo. The token's level of access determines how much information Mondoo can retrieve. Supply your personal access token to Mondoo by setting the GITHUB_TOKEN environment variable. To learn how, read https://mondoo.com/docs/cnspec/saas/github/.
+
+	If you have very large GitHub organizations, consider giving Mondoo access using custom GitHub app credentials. To learn how, read https://mondoo.com/docs/cnspec/saas/gh-app/.
+
+	If you have a GitHub Enterprise Server account, you must provide the URL for the account using the --enterprise-url flag.
