 Your DigiLED shield is complete!
-**Note:** On the back of the shield there is a solder patch to activate pin 5 instead of pin 1 as the digital input.
+**Note:** On the back of the shield there is a solder patch to activate pin 5 instead of pin 1 as the digital input.  If you are not using the DigiLED as a shield onto the DigiSpark Pro and planning on running it at a distance, you only need to connect the specified digital pin (Pin 1) and bottom 3 pins (5V, GND, VIN).  You do not need to connect all 6 pins on the right-hand side of the shield.
+=====Chaining:=====
+When chaining multiple DigiLED's together, you only need to connect 3 points as a daisy chain using VCC, DO>DI and GND.
+For example, LED #1 would need the top 3 pins VCC, DO (out) and GND to connect to DigiLED #2's VCC, DI (in) and GND on the second row from the bottom of the board.
+If you added LED #3 you would need to connect DigiLED #2's top three pins to the second row from the bottom on DigiLED #3 and so-on and so forth.  After DigiLED 1, the side pins and 5V, GND, VIN should not be connected, only the three input and output points for chaining.

+If you have a single DigiLED, the following code sample will make it continuously cycle through white, cyan, violet, yellow, red, green and blue.

+If you have more than one DigiLED daisy-chained, the following code will make all the DigiLEDs light up green. You need to change the NUMPIXELS variable to the number of DigiLEDs you have chained together.
