First grab those resistors! They're the blue things with the stripes. You'll want to bend them like in the picture below, then push them through the board where it has rectangles with Rs in them. Once they're through bend the legs back so they stay in the holes without too much movement. Do this for all four resistors and for your own sanity line them up the same way, or make a conscious effort to alternate them. It will probably annoy you if you don't. Worse it will annoy me, so please make sure you arrange them nice!



Got that? Now head back in time about 3 minutes and plug in your soldering iron. You want the tip nice and hot, so it will melt a bit of solder without hesitation, might need to clean the tip a bit with your scouring tip cleaner if you've not used your iron in a while / ever.



Use the tip to heat the pad (that's the metal bit on the PCB) and the leg of the resistor a little bit then push the end of the solder onto where the leg and pad and soldering iron meet. The solder should flow into the hole and around the leg of the resistor. Pictures of that are below. Now repeat for all the legs. You want to get enough heat into the pad and the part to allow you to melt solder in their vicinity. Resistors are hard to damage with heat so get your technique right here. Don't worry though you're going to have more time to practice before we get to anything that you can easily kill with a bit of heat.
