updating firmware instructions (not using a pencil)

i really wasn't a fan of scribbling a pencil over the jumper to switch into bootloader mode and then cleaning it up carefully - it's a way easier to use a second pair of hands and a usb extension cable. so here's how i did it:

1. inserted my pico into an USB extension cable - the other end is not connected to a PC yet
   
2. opened nail scissors as much as was needed to short the contacts
   
3. at the same time i was pressing the button (on pico)
   
4. asked my wife to put the other end of the extension cable into a PC
   
5. voila! :-)
   just sayin..
