Advice on importing supplier pricelist

Hello,
I don’t seem to quite understand the workflow in importing my price list from suppliers as described in the documentation:

The format of my pricelist is
ProductGroup, ProductType, ItemCode, ItemName, Price
Lexmark, Lexmark Inkjet Cartridges, L10N0016E, LEXMARK 16XL BLACK INK CARTRIDGE FOR X1110 X1130, 570.50
.
.
HP, HP Inkjet Cartridges, L10N0016E, HP 16XL BLACK INK CARTRIDGE FOR X1110 X1130, 570.50
.
.
How should I go about importing this into erpnext?
On a monthly basis a new pricelist is sent and how should I go about updating it - can I keep the old price list as “history”

Zizi
