The main steps for enabling ACME support in short summary are:
1. Allow Synapse to listen on port 80 with authbind, or forward it from a reverse-proxy.
1. Set `acme:enabled` to `true` in homeserver.yaml.
1. Allow Synapse to listen for incoming ACME challenges.
1. Enable ACME support in `homeserver.yaml`.
1. Move your old certificates (files `example.com.tls.crt` and `example.com.tls.key` out of the way if they currently exist at the paths specified in `homeserver.yaml`.
1. Restart Synapse

### Config file editing
Once Synapse is able to listen on port 80 for ACME challenge
requests, it must be told to perform ACME provisioning by setting `enabled`
to true under the `acme` section in `homeserver.yaml`:

### Starting synapse
### (Re)starting synapse
Ensure that the certificate paths specified in `homeserver.yaml` (`tls_certificate_path` and `tls_private_key_path`) do not currently point to any files. Synapse will not provision certificates if files exist, as it does not want to overwrite existing certificates.
