 These are the steps to install Qt on a single Pi from the host. The `.deb` package for the Pi can of course easily be copied to and installed on any number of your devices.
 
- * First, copy the Qt `.deb` installer from your build host to your Pi:
-
-   ```bash
-   scp qt-everywhere-opensource-rpi_5.9.4_armhf.deb pi@raspberrypi:

+```bash

-   ```bash
-   ssh pi@raspberrypi

- * Install Qt and all its missing dependencies (note the use of `apt` instead of `apt-get`):
