-## Notes
+## Notes on Programing
+The Unicorne PCB comes pre flashed with a QMK via map, to be used with [VIA](https://usevia.app/).
+You can use [QMK Configurator](https://config.qmk.fm/#/boardsource/unicorne/LAYOUT_split_3x6_3) to reprogram your keyboard.
+
+And of course you can swap over to BS-python and use peg, [here](https://peg.software/docs/board-update) is guide on how to do that.
+then you can plug it into peg and let it take care of the rest.
+
+## Lets Talk About Getting Into The Bootloader
+Being that its flashed With QMK by default you can hold down the top left key as you plug it in, this will put you into bootloader. 
+And there is the classic that will always work of holding down the boot switch and pushing the reset switch then letting go of the boot switch.
+
+The boot and reset switches are labeled on the PCB, but we will stat it here too. 
+Boot is the right most switch rest is the left most switch. 
 
+This is a rp2040 keyboard so you never need to use QMK Toolbox. 
+As soon as you get your keyboard into bootloader it will show up as a drive named "RPI-RP2" now you can drag and drop your new keymap onto it.
