I trying to go in order of height when soldering components. I start with resistors because they are closest to the board.

If you're having trouble keeping the board from moving when soldering you can use a piece of tape to hold the board down. Just be sure not to have the tape too close to where you are soldering your joint!

If you're confused about which side is positive or negative, we added a reference in silk screen at the bottom of the board!

The switch is easy to bridge so be sure to not use too much solder!

*Note: The switch is made of metal so it gets hot when soldering. Be careful touching it during and directly after soldering!

The battery holder should "click" into place which makes it easy to solder!
