Steps to reproduce:

1. Go to the pages above.
2. Look for AIX specific starting/stopping instructions, the Agent on Unix-like systems and the if installed as package instructions sections that would apply to AIX.

Result:
There are no AIX specific instructions just Unix like instructions that don't actually cover the AIX specific installation paths. 

Expected:
To see either an AIX specific section, or under the Unix-Like section things somethings specific to AIX similar to the  "On other systems you may need to run: /etc/init.d/zabbix-agent start"  wording that is along the lines of  "for AIX systems you need to run: /etc/rc.d/init.d/zabbix-agent start"  and then some stop restart status type commands for AIX as Well. 

Rational:

System V/init.d is not the default AIX service control systems and AIX system keep their rc scripts/init.d stuff in a different path than the example init.d stuff. 

Additionally, Not having AIX specifically mentioned was problematic during our paid installation engagement, that just ended. The question of how to stop and start the AIX binaries came up and our zabbix installation rep whom did not have experience with AIX pointed me to this 7 year old git hub repository to set up automatic setup https://github.com/digiaiiris/zabbix-agent-aix/blob/master/zabbix-agent . However while working though how to do it I realized that it was installed in the AIX location for init.d rc stop start scripts and that I just needed to start it via those methods. 

Had this specifically been documented it might have been saved time for both me and your implementation staff.
