Mount it somewhere in the file system, format it (or does one have to
format first -- you'll likely want it to be in ext3 or ext4 rather than
native FAT32 so Linux protection and modes are active). Depending upon what
you need storage for, you might move all of /home to the SD card, or
partition it for /home and /var, and mount those partitions over the
original.
You'd want to make the mounting operation automatic via lines added to the
fstab file. Maybe need to set privileges so user accounts can access.
