-Public ACM certificates can be installed on Amazon EC2 instances that are connected to a [Nitro Enclave](./acm-services.html#acm-nitro-enclave). You can also [export a public certificate](./export-public-certificate.html) to use on any Amazon EC2 instance. For information about setting up a standalone web server on an Amazon EC2 instance not connected to a Nitro Enclave, see [Tutorial: Install a LAMP web server on Amazon Linux 2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-lamp-amazon-linux-2.html) or [Tutorial: Install a LAMP web server with the Amazon Linux AMI](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-LAMP.html).
+To automate public certificate issuance and renewal outside integrated services such as on Amazon EC2 instances, use the ACME protocol. For more information, see [ACME certificate automation](./acm-acme.html). Alternatively, if you cannot use ACME, you can automate exportable certificates issued from ACM through [AWS Workload Credentials Provider](./acm-certificate-automation.html).
