Install my own certificate

I have a domain of my own and I want to point to a new server with jitsi server. In the jitsi installation process, how do I install the certificate and the public key that I already have?

When installing there is an option you can choose which asks you for the key and the certificate file.
Also if you are using apache2 or nginx (installed before installing nginx), if you already have installed with self-signed certs, you need to open jitsi-meet web configuration and change the paths of the certificate files and restart the webserver.

All is ok now. Thank you.
