Cloud9 is a free IDE available from https://github.com/ajaxorg/cloud9/ under GPLv3. I would like to use this to set up a service like https://c9.io/. The Cloud9 documentations do not mention anything about it. The Cloud9 documentation assume a sing user on localhost or bind to another address without one hard set username and hard set password.

How do I run cloud9 IDE on my computer allowing multiple users? Are there any documentations?

This is the closest to what I found - https://github.com/avgp/cloud9hub (for multiple workspaces)
