+# IDNs are currently not supported (Only domain names that follow the [A-Za-z][0-9]()*+,-:;<=>?@[]^_|~. regex are supported)
+#
+# As ClientSSL profiles do not support * in their names, domain names with wildcards are replaced with a _ character, which can result in a conflict if a domain name similar to _.example.com is used
+# however you can set a custom ClientSSL profile name to workaround this issue or use a regular subdomain as CN with wildcard or _ as alternative name
 #
 # All of the environment variables are optional
 # DEPLOY_F5_BIGIP_CLIENT_SSL_PROFILE_DISABLE = yes/no - Whether to create ClientSSL profile or just install the cert/key/chain into certificate store (defaults to: no)
