"3. solder the outputs of the 555 oscs to the pins."

Could somebody describe this in a little more detail

Does this mean after you cut one of the pins, i.e. pin 56, the output
of the 555 goes in series with (in between the cuts you just made)
pin 56, or does one side of the 555 goto one side of the cut, and the
other to ground or some other pin

Thanks!
