 # What is Torch?
 Torch is the successor to SE Server Extender and gives server admins the tools they need to keep their Space Engineers servers running smoothly. It features a user interface with live management tools and a plugin system so you can run your server exactly how you'd like. Torch is still in early development so there may be bugs and incomplete features.
