==== Official Client ====

If you're using the official Let's Encrypt client, assuming you have your certificate in ''/etc/letsencrypt/live/example.org/'', here is how you can make a ''znc.pem'' from it (concatenate the 3 files together):

 cat /etc/letsencrypt/live/example.org/{privkey,cert,chain}.pem > znc.pem

You need to repeat this every time you obtain a new certificate.
