When do I need to rebuild initrd (the initial ramdisk of Linux)?

Question

Background: I am developing a DKMS package for my kernel module. The DKMS man page contains the following sentence:

REMAKE_INITRD = This directive determines whether initrd should be restored after installing the module on the kernel.

Question: When do I need to redo initrd? How do I know if initrd needs to be rebuilt after installing my module on the kernel?
