Camunda standalone process engine installation

I see the option of changing the DB , LDAP, etc. settings for the tomcat deployment model from this doc - Install the Standalone Webapplication (.war) | docs.camunda.org

But if I want to install the engine using the zip file (Camunda Platform Download Hub | Camunda) and then using ./start.sh to start, I do not find the. option to change database or LDAP configuration. Can someone please point me to the correct place to change configurations for this mode of installation?

thank you!

The main distribution on the download page points to Camunda Platform Run.
It’s actually much easier to setup a new datasource and change settings. It basically all be done in the configuration file. You can read more about it here:
