The purpose of 'repeat' is to start a loop. To use it, all you have to do is write 'repeat' in a script and press enter on your keyboard. After you've done that you should see a bit of space from the beginning of the line. Don't remove that, otherwise the script won't work. Ignore the blank space and write your script, don't forget to add wait() or task.wait() to your script or it won't work. Now you have to find an end to the loop.
