Problem on learning genieACS

hello, I am doing an internship in auto provisioning, I created a VM with an ubuntu server 20.04 LTS and I installed nodejs, MongoDB and genieACS, now I have a real problem I can’t find enough documentation resources on genieACS (creation of scripts and integrating them on the genieACS) please give me links or direct me to resources that will help me.
thank you in advance.
