-  - Download this file: https://github.com/majbthrd/DapperMime/releases/download/20210225/raspberry_pi_pico-DapperMime.uf2
-  - Boot the Pico in bootloader mode by holding the bootset button while plugging it in
-  - Open the drive RPI-RP2 when prompted
-  - Copy raspberry_pi_pico-DapperMime.uf2 from Downloads into RPI-RP2
-  - Connect the debug pins of your CMSIS-DAP Pico to the target one
-      - Connect GP2 on the Probe to SWCLK on the Target
-      - Connect GP3 on the Probe to SWDIO on the Target
-      - Connect a ground line from the CMSIS-DAP Probe to the Target too
+Download one of these firmware files:
 
-  If you have good wiring between your Pico's, you can instead use rust-dap for faster programming:
