Ansible Automation Platform 2.5 installation

Hi all,
I’m new in the community and in Ansible.
I 'm looking for effective documentation describing essentials steps, tip and tricks to make a basic installation of Ansible Automation Platform 2.5 from scratch. Any suggestions is appreciated.
Thanks

Thanks for help.
Now installation task stops with errors because of the following certification error:

fatal: [gateway]: FAILED! => {“changed”: false, “msg”: “There was an unknown error when trying to connect to ParseResult(scheme=‘https’, netloc=‘bbpmdrant004lx.network.group:8443’, path=‘api/gateway/v1/’, params=‘’, query=‘’, fragment=‘’): URLError <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1133)>”}

Can you suggest a way to ignore self-generated certification?
I’ve got no positive results applying official documentation, so every suggestions are appreciated.

Either, if someone could tell me what kind of certification is needed to successful complete the installation is also better appreciated.
