about livesplit in streams the livesplit work automaticly or the streamer make the timer on and off if if its by the streamer, how can i make my livesplit work automaticly?

LiveSplit works normally by the use of hotkeys to make the program start, stop, reset, and more. The "Global Hotkeys" function can be helpful if you ever decide to go down this path.

If you want it to work automatically, you'll need an Autosplitter. It's basically a script custom tailored for the game that knows when to move the splits along. Information can be found about them here: https://github.com/LiveSplit/LiveSplit/blob/master/Documentation/Auto-Splitters.md

If you're running popular games, check around first as someone likely might have made one for it. It can save you a whole lot of trouble.
