How to Wiring

Sorry for this question if it is stupid, but how can I wire the led to beaglebone? 

I want to setup the beaglebone with WS2812B Leds, looked at output of:
  node pru/pinmap.js --mapping pru/mappings/rgb-123-v3.json 

but what all the green numbers mean?

On the led I've 3 wires from LEDs: +5V, GND that goes to power supply and DI that goes to beagle bone with the logic level shifter.
