1. Follow the instructions in the [Raspberry Pi setup guide](https://projects.raspberrypi.org/en/projects/raspberry-pi-setting-up) to set up your Pi, connect it to a keyboard/mouse/monitor, connect it to your WiFi or ethernet network, and update the software.

To program the Pi using the Grove sensors and actuators, you will need to install an editor to allow you to write the device code, and various libraries and tools that interact with the Grove hardware.

One of the powerful features of Python is the ability to install [Pip packages](https://pypi.org) - these are packages of code written by other people and published to the Internet. You can install a Pip package onto your computer with one command, then use that package in your code. This Grove install script will install the Pip packages you will use to work with the Grove hardware from Python.
This starts by installing Git, along with Pip to install Python packages.

The Seeed Grove Python packages need to be installed from source. These commands will clone the repo containing the source code for this package, then install it locally.
> 💁 By default when you install a package it is available everywhere on your computer, and this can lead to problems with package versions - such as one application depending on one version of a package that breaks when you install a new version for a different application. To work around this problem, you can use a [Python virtual environment](https://docs.python.org/3/library/venv.html), essentially a copy of Python in a dedicated folder, and when you install Pip packages they get installed just to that folder. You won't be using virtual environments when using your Pi. The Grove install script installs the Grove Python packages globally, so to use a virtual environment you would need to set up a virtual environment then manually re-install the Grove packages inside that environment. It's easier to just use global packages, especially as a lot of Pi developers will re-flash a clean SD card for each project.
Finally, this enables the I<sup>2</sup>C interface.

Enter `Y` when asked to confirm. Then re-launch PowerShell and try again.
You can reset this execution policy at a later date if needed. You can read more on this in the [Execution Policies page on Microsoft Docs](https://docs.microsoft.com/powershell/module/microsoft.powershell.core/about/about_execution_policies?WT.mc_id=academic-17441-jabenn).
