OpenLDAP installation. Am I missing something?

I may have this totally wrong but why is there no installation documentation that tells somebody how to setup OpenLDAP the right way. After installing OpenLDAP you have no slapd.conf file so that direction is not happening. If you modify any file in the slapd.d directory, startup will complain about bad checksum. Yes I know you can regenerate the checksum and fix that but why? I can't find any where that tells you how to modify the base dn, rootdn, and root password without editing the files in the slapd.d manually. Am I missing something? I have check Google, Youtube, and other places and they all say manually edit files in slapd.d. That can't be the right way if openldap server is complaining about doing it.
