Hi, 

I am not able to create a wiki page in my confluence. The help given on the confluence is not clear about that can some please help me with it. Can I use wiki page to create a page like https://docs.bmc.com/docs/cloudlifecyclemanagement/46/configuring-after-installation-669198571.html. If yes, how?

Thanks in advance!
