Hi, welcome to Scratch on Scratch. Put whatever code down and delete any code you want! to delete all the code click delete code and type in all, and it will delete all the code in the list. click the stuff under the username and click sign out. that was just to make it realistic. You can name your project by clicking the white part under the untitled to name it.
Thanks to @arman819 for helping me fix some glitches
