What you want to do is start livesplit, open the splits file, edit the split names if you want. You can edit the layout as you wish of course, it doesn't really matter but linked mine if someone wants it. There are cool things like graphs etc if you want that kinda stuff, couldn't fit one for my layout. Autosplitter is going to be added to the layout. Left click the livesplit window, click "edit layout", click the huge "+" --> "control" --> "scriptable autosplitter". After that you double click on the "Scriptable Auto Splitter" thingy and add the .asl file i linked. You should instantly have the "start" and the "split" tickboxes available. Keep them active to make them work, you can disable either if you don't want it to start automatically or split automatically for some reason. In any case, the autosplitter should work, the timer automatically starts when you enter warm up and every time you touch the flower it splits and you continue to the next segment. Menu times and flower waits are included in the splits, that's just how it is. I also recommend testing out how the splits work.
