I want to use blockcert but how does one generate a template design before creating an unsigned certificate using cert-tools? Is there any documentation or guide on how the displayHTML works or how to use it to design the certificate.

Is it possible for one to design or create a template before doing a batch certificate creation in cert-tools? If there is what is the process?
