Congrats on your new baby!
1) If your kit came with two of everything, make sure to charge one of the batteries right away. Just be sure to not screw it onto the charger tight (I keep the one end hooked up to the USB port and I stop twisting the battery when it starts blinking).
2) Shake up your juice of choice, and drip onto the filler in the cartridge. Go slowly, allowing it to absorb (you can use a toothpick, or similar, to 'burp' the air out of the filler after adding each drop). Stop when the top of the filler looks wet but isn't yet pooling with juice, about 10-15 drops on average. If you've added too much, use a napkin or paper towel to absorb it a little.
3) Blow out your atomizer onto a paper towel, several times. I hold the towel onto the battery end of it, then blow very hard through the open end. I also add a few drops of juice and repeat the process.
4) Screw the atty onto the battery, but not at all tightly. Add a drop or two of juice.
5) Put the cartridge onto the atty (some people line up the semi-rectangular shape of the cartridge with the white portion of the atomizer...but don't stress about it).
6) Take sort of long and slow drags to start...this is not the same action as dragging on an analog.
