First time installing question

I’m hoping to install Marlin on an Ender 3 S1.

For installing, there’s seem to be two files to download, “Ender3-S1-STM32F4-20221012.bin” and “Ender3-S1-MarlinUI-STM32F4-20221012.bin”. Do I just put both of those files on a blank SD card and insert it into the printer, and that’s the whole process?

Edit: I think I figured it out. They’re just two different firmwares. The one that isn’t MarlinUI had a glitchy interface, but MarlinUI seems to be ok so far.
