+## Making your own sketch
+Lets try and set up an empty sketch using the template below:
+
+		OPC opc;
+
+		void setup() {
+  		size(500, 500, P3D);
+
+		  opc = new OPC(this, "127.0.0.1", 7890);
+		  opc.ledGrid8x8(0, width/2, height/2, height / 16.0, 0, false);
+		}
+
+		void draw() {
+		  background(0);
+		}
+
+Here the important part is the ledGrid8x8 line. First we have a 0, this indicated that we have connected the led matrix to connector 0 on the fadecandy. Next we need to define the center of the matrix. This is done using `width/2` and `height/2`. We also need to define the spacing between each LED. The spacing is approximately one LED in size, so we can use `height/16`. The next 0 is the rotation. Since we just use the default rotation we dont need to change this. `false` means that all the LEDs point in the same direction.
+
+If we run this nothing will really happen except we get a black screen with 8x8 dots on.
+
+We can change the individual colors using `setPixel(index, color)` in the draw function.
+
+
+		opc.setPixel(0, color(255,0,0));
+
+The above code changes the color of the first pixel to red.
+
+		opc.setPixel(10, color(0,255,0));
+
+The above code changes the 11th pixel to green.
+
+This should make sense and be easy to work with.
+
+Unfortunately each pixel does have a bit of color bleeding to nearby pixels, this can be prevented using a printed separator or another time of plate in front.
+
+## Another example
+
+It is easy to test and identify different fadecandy's using the port the fadecandy is set up to. Just go to `localhost:port` and play around
