What needs to be done

The actual setup process for a BE-IIS system is intentionally simple.

The goal is not to manually configure kernel drivers, write device tree overlays, or debug low-level integration issues.
Instead, the system is prepared using standard Raspberry Pi steps, followed by a structured installer workflow.

Source: This workflow is based on the BE-IIS installer documentation.

Overview

Prepare a Raspberry Pi OS Lite image\
Flash the SD card\
Enable SSH and create a user before first boot\
Boot the system and connect via SSH\
Install Git\
Clone the BE-IIS installer repository\
Run the installer

Step by step

Prepare Raspberry Pi OS

Start with a minimal Raspberry Pi OS Lite installation.

Flash the SD card

Write the operating system image to the SD card.

Enable access

Before the first boot:

Enable SSH\
Create a user

Boot and connect

Start the Raspberry Pi and connect via SSH.

Install Git

sudo apt update
sudo apt install -y git

Clone the installer

git clone https://github.com/be-iis/be-iis-installer
cd be-iis-installer

Run the installer

./scripts/install/install-all.sh

Why this is simple

The process follows a clear structure:

standard Raspberry Pi setup\
no manual kernel or device tree work\
automated integration via the installer

This allows users to focus on their application instead of system bring-up.
