 **fair warning**
 >Use of the arduino bootloader *does* assume that your circuit has a USB port available, as well as a 32.678kHz clock on the RTC Xout / Xin pins. During cycles, the bootloader (assuming it is on a Feather M4) will toggle 'D13' (PA23) as well as send Neopixel Data to (?).
 
-To get started, find the latest build of the [adafruit bootloader] and download that (probably a `.bin` or `.elf` or `.hex` file).
+To get started, find the latest build of the [adafruit bootloader](https://github.com/adafruit/uf2-samdx1/releases) and download that (probably a `.bin` or `.elf` or `.hex` file). The Adafruit Feather M4 uses the SAMD51J19A, so grab that one for the current generation squidworks module.
 
 We need to write this file into the micro's memory. I have been using the `Serial Wire Debug` interface, which is enabled by default on the D51 hardware (but JTAG is also available, but requires an enable pin pulled low somewhere *I think*). `SWCLK is on PA30` and `SWDIO is on PA31`.
