There are two different capacitors in the kit.   This is C1, a ceramic capacitor.  It has a little yellow body and two long leads:

The electrolytic capacitor -- the fat cylindrical one -- will go in location C2:

This capacitor has polarity. It must be installed with the minus on the cap to the minus on the PCB, as shown here:
  
And this is C2, an electrolytic capacitor. It has a short, cylindrical body:

Just as before, bend the leads outward, solder, and clip.

Next, we'll add the ceramic cap to location C1:

This one can be installed in either direction.

Insert the little ceramic capacitor into C1, with either orientation. 
 
  
C2, the electrolytic capacitor, has a polarity.  It must be installed with the "minus" side -- marked by the large white stripe on the side -- to the "-" side on PCB, as shown above.

The board so far:
  
Just as before, bend the leads outward, solder, and clip the leads of both capacitors.
