All good advice. To add some thoughts, keep the nuc cool and out of the sun while screened. Without knowing exactly how crowded the nuc might be, it is hard to advise, but cool is good, hot is bad.
Once home, set the nuc where you plan to install it and open the entrance. Allow the bees to fly a while. When they settle down, then they are ready to transfer. You can wait a day or two. No worries.
When ready to transfer, place the nuc and the new hive side by side, touching, with the nuc closer to you. (You are on the side, not front or back). For a beginner, the new hive should have all frames removed so there is lots of room.
If you have allowed the bees to settle, they should not be runny and you will need a minimum of smoke, if any. When smoking, waft a little smoke gently over the bees you wish to calm and watch the result. They should withdraw a bit, but not run.
The others have covered some of the details, and if the frames are loose, the job is easy. Simply lift each frame, one by one from the nuc, starting with the closest and, reach over the nuc and place each frame in the same orientation and same relative position into the brood box box. Don't worry about spacing at this point. Your goal is to reassemble the nuc in the hive exactly the way it was in the nuc box. Some suggest inserting extra frames if the nuc was crowded, but you are up north, and as a beginner, that is a bit of an advanced operation. I'd advise against for now. The bees will be fine regardless, and you won't be risking brood loss due to chilling.
When all the frames are in the new hive, then slide them together in the middle if they are not already. I'm assuming that the frames are self-spacing, but if they are not, make sure the spacing is about the same as in the nuc. If you have frame spacers in hive and not in the nuc, don't worry. The spacing is fine. If the nuc has spacers and your hive does not, just do the best you can.
When the nuc is positioned in the middle of the box and looks about the way it did in the nuc, add the outside frames and close it up. If all the frames don't fit, leave one or two out for now. Don't worry, you can adjust things later.
OK. You are done. You did not waste time looking for the queen, but maybe you got to see the brood. If you have looked at pictures of healthy brood, then you'll have an idea if you have brood in all stages, if the patterns are reasonably solid, and if all is well.
If you have a digital camera, taking pictures of the frame faces as you transfer will allow you to study the brood and see the queen later on your computer and you'll have a record if you want to ask advice, or if you think you should complain to the supplier. Having a helper take pictures of each side of the combs as you handle them is ideal, but not everyone has brave friends.
You don't need to spray with syrup, and doing so can make the job more difficult. If you notice that the frames are very light and you don't see any honey anywhere, after the hive is transferred, add a syrup feeder.
Once the bees have settled a day or two, you can go back at your leisure in an early afternoon on a nice day and do an inspection. The bees will be calm and you will have more confidence.
