How to set up SD Card for SIDE2 with APT, FAT16, and FAT32 partitions

I've seen various posts on the BBS's with questions around setting up SD Cards for SIDE cartridges. I originally wanted to create one for my own SIDE2 that had APT partitions (like a hard drive for the 8-bit in SDX), FAT16 partitions (to transfer files from PC and read them in SDX), and a FAT32 partitions (to access games and programs using the SIDE Loader). It took a while to figure it out and some help from Jeff W., but I put together step-by-step instructions on how to do it so I don't forget it again. I have attached them to this post in case it's helpfull to anyone else.
