 You create an object with the parameters number of LEDs, state machine ID, GPIO number and mode (RGB or RGBW) in that order. So, to create a strip of 10 leds on state machine 0 and GPIO 0 in RGBW mode you use:
 
 ```
-from neopixel import neopixel
+from neopixel import Neopixel
 
-pixels = neopixel(10, 0, 0, "RGBW")
+pixels = Neopixel(10, 0, 0, "RGBW")
 ```
 
+Mind that you can use whichever order of RGB / RGBW you want (GRB, WRGB, GRB, RGWB ...). This only represents order of data sent to led-strip, all functions still work with RGBW order. Exact order of leds should be on package of your led-strip. (My BTF-lights sk6812 has GRBW)
+
 This class has many methods, two main ones being show() which sends the data to the strip, and set_pixel which sets the color values for a particular LED. The parameters are LED number and a tuple of form (red, green blue) or (red, green, blue, white) with the colors taking values between 0 and 255.
 
 At the moment, this isn't working with the interpreter, so you have to run it from a file. Looks like it's running just too slow to keep up with the PIO buffer from the interpreter. The key methods are set_pixel(n (r,g,b)), set_pixel_line(p1, p2, (r, g, b)) which sets a row of pixels from pixel p1 to pixel p2 (inclusive), and fill((r,g,b)) which fills all the pixels with the color r, g, b.
