could anyone explain me what has to be done to update my registered account E-Mail?
I am not using certbot, so i cannot use the certbot command. I am using a php client on base of acmephp (https://github.com/acmephp/acmephp).
But acmephp does not seem to have this implemented, so I would like to know what needs to be done to implement it myself and if possible provide a PR for acmephp.
I tried to find out in the source of certbot, but it is quite hard to understand for me there.
Thanks for your help!
