 With that information, we can make an educated guess of what type of battery we should get. For example, a battery with more capacity, let's say 600 mAh, would in theory last for twice the period.

+## Software Setup
+
+The software setup involves two steps: **upload a sketch** and **insatlling nRF Connect for Desktop**. 
+
+### Upload Sketch
+
+This step is rather straightforward. Upload the sketch that you want to measure the power consumption of. Below is a minimal sketch that reads an analog pin continuously. 
+
+```arduino
+
+```
+
+### Install Desktop App
+
+To measure the power consumption, we are going to use the [nRF Connect for Desktop](https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-Desktop/Download) tool. This is a program that you install on your computer.
 
 ## Hardware Setup
 
-## Software Setup
+The profiler we used is the [Power Profiler Kit II](https://www.nordicsemi.com/Products/Development-hardware/Power-Profiler-Kit-2).
+
+1. First disconnect the USB cable from your board. You will be powering the board directly from the power profiler, so there's no need for the USB cable at this point.
+2. Use the provided cable from the kit, and connect it to your board's GND and power pin, following the illustration below:

+![Connect the power profiler to the board.]()
+
+***Important note! In the software setup you enable the "Power Output" of the power profiler. Make sure that the voltage (3.3 V or 5 V) matches the voltage on the power pin of the board. Applying 5 V to a 3.3 V pin will damage your board.***

+With the hardware and software set up, let's take a look at how to record the power consumption of your device.
