 ### Software installation
 
 Note that resonance measurements and shaper auto-calibration require additional
-software dependencies not installed by default. First, you will have to run on
-your Raspberry Pi the following command:

+Next, in order to install NumPy in the Klipper environment, run the command:
 ```
 ~/klippy-env/bin/pip install -v numpy
 ```
-to install `numpy` package. Note that, depending on the performance of the
