No problem, glad I could help.
For the moment we do not have any official documentation on room server managers except for that repository. Do you plan to make your own room server manager? If so we can probably put together some documentation for that. Otherwise for now, the only request you have to account for is that POST request to /findRoomServer as detailed in the source code for the Room Server Manager DevTool. This DevTool is intended to be used to test room servers more easily and have access to their logs faster. But if you plan to make an actual room server manager that can launch and manage multiple servers at once, you can use this tool as a base and build up on it to add logic for managing multiple server instances.
