That will make an excellent summer (unless you insulate the sides) pond. Dechlor it and re-test in a week to make should the chlorine isn't impregnated in the liner. You'll have to get some biological filtration going.That won't be much of a problem tho. A large W/D will be easy to make< maybe with a waterfall return.
What do you want to stock in it? If it's a summer only pond you'll need a place to winter the fish.
If you want to make it a year 'round pond, dig a hole and bury it, you need to at least go past the frost line, then use the excess dirt to berm around the top half to help insulate it.
