+<pre>
+# pileds act
+</pre>
+
+<p>
+	Pileds also provide example and usable commands for Adafruit 7segment
+	LED Backpack and the 8x8 LED Matrix. Creating visual elements with
+	Kids is very fun and let them train mathematics in the ame sime since
+	the leds must be mapped (ie: 0, 3) on a gride. Let's display a nice

+# pileds 8x8 --boat
+# pileds help
+</pre>

+	PiLeds use some example code from Adafruit and PiClass Git Hub 
+	repositories. We have packaged them for easy install/update and
+	to provide some code right under the hand. Adafruit and PiClass
+	code examples are located in:
