Adjusting Boot Options in rEFInd

I am trying to follow these instructions from a post 4 years ago. I need to adapt them to Mint. Where do I get the following entries?:

loader – The one I entered below it’s just a guess. initrd – The one I entered below it’s just a guess. options – Where do I get all the IDs numbers here from?

menuentry Mint { icon EFI/refind/icons/os_linuxmint.png ostype Linux volume boot loader /vmlinuz-linux-mint initrd /initramfs-linux-mint.img options "rw root=UUID=33bfccef-ae34-4044-a74a-9d8f9e4fde53 quiet elevator=bfq resume=UUID=f3b2e20c-8e7c-4ab4-8304-68ef1ae3773b resume_offset=1189888" } 

Here is an example of the refind.conf file

Thanks guys
