 # For GitHub Enterprise Cloud organizations that have SAML configured at the organization level, this query will print out a list of the first 100 SAML identities (specifically the `nameid` attribute value in these SAML identities) in the organization and the GitHub username linked to them.
 # This query can be used to see which users in a GitHub Enterprise Cloud organization have a linked SAML identity.
 # This query will not print out a user username (`login`) value if there is not a GitHub user account linked to this SAML identity. 
+# If there are a large number of identities/users (greater than 100), pagination will need to be used. See https://graphql.org/learn/pagination/ for details on pagination.
