Jibri step-by-step install

Hi everyone, I’m a new Jitsi user.
I would also like to install Jibri: I have tried numerous guides found on the internet and on the Jitsi community but have never been able.
Is there an official guide on how to install jibri?

My jitsi architecture is:

  • Ubuntu 18.04 server behind NAT
  • internal firewall not configured
  • GoDaddy wildcard SSL certificate
  • Jitsi with prosody authentication enabled for room creation.

For Jibri I would like to create another Ubuntu 18.04 server

If anyone can help me with a step-by-step configuration, I would appreciate it.
