## What is an instance ID, and where do I find it?
The instance ID is the name of the folder where your instance is contained.
To find it, **right-click** on the instance you want to know the ID of, and then click on _Instance Folder_ within the context menu.
Now, just copy the name of the folder that opened.
## ProjT Launcher is still opening after I close Minecraft
Currently, the _Close ProjT Launcher after game window opens_ option opens ProjT Launcher after closing Minecraft, even when launched from the CLI.
To disable this, open _Settings_, then select _Minecraft_, and finally, un-check _Close ProjT Launcher after game window opens_ or check _Quit the launcher after game window closes_.
