Setting up a home partition on a separate drive

Okay I have 60GB SSD..And i want to install Linux Lite 64bit on my machine to see can it replace Windows for me..So I was wondering how to mount my home directory on my 1TB HDD....

sda = ssd

sdb = hdd

sda1= swap - 4 GB

sda2= / - rest of the ssd (fstab: add discard for trim, see older post for where and how)

sdb1= /home, ecrypted with dm-crypt+LUKS, entire hdd

bootloader: set to sda

sda2 flagged as boot

voilà
