+        How to make this work:
+
+        - Obtain a NUCLEO-STM32WB55 from your preferred supplier.
+        - Download and Install STM32CubeProgrammer.
+        - Download stm32wb5x_FUS_fw.bin, stm32wb5x_BLE_Stack_full_fw.bin, and Release_Notes.html from
+          gh:STMicroelectronics/STM32CubeWB@2234d97/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x
+        - Open STM32CubeProgrammer
+        - On the right-hand pane, click "firmware upgrade" to upgrade the st-link firmware.
+        - Once complete, click connect to connect to the device.
+        - On the left hand pane, click the RSS signal icon to open "Firmware Upgrade Services".
+        - In the Release_Notes.html, find the memory address that corresponds to your device for the stm32wb5x_FUS_fw.bin file
+        - Select that file, the memory address, "verify download", and then "Firmware Upgrade".
+        - Once complete, in the Release_Notes.html, find the memory address that corresponds to your device for the
+          stm32wb5x_BLE_Stack_full_fw.bin file. It should not be the same memory address.
+        - Select that file, the memory address, "verify download", and then "Firmware Upgrade".
+        - Select "Start Wireless Stack".
+        - Disconnect from the device.
+        - In the examples folder for stm32wb, modify the memory.x file to match your target device.
+        - Run this example.
+
+        Note: extended stack versions are not supported at this time. Do not attempt to install a stack with "extended" in the name.
