What You Need

Required Hardware

Raspberry Pi Board

Recommended:

• Raspberry Pi 5
• Raspberry Pi 4
• Raspberry Pi Zero 2 W

Power Supply

Raspberry Pi 5

Use the official:

• 27W USB-C power supply (5V/5A)

Underpowered USB-C chargers can cause instability or USB issues. oai_citation:2‡Raspberry Pi

Storage

Recommended in 2026

Best Option: NVMe SSD

For Raspberry Pi 5:

• Faster boot times
• Better reliability
• Improved Docker/database performance

Alternative: microSD Card

Recommended:

• 32GB or larger
• A2-rated cards preferred

Cooling

Raspberry Pi 5 runs hotter than earlier models.

Recommended:

• Active cooler
• Fan case
• Heatsink

Monitor and Accessories

You may also need:

• HDMI or micro-HDMI cable
• Keyboard
• Mouse
• Ethernet cable

Step 1: Install Raspberry Pi Imager

The easiest installation method is Raspberry Pi Imager.

Download it from:

Raspberry Pi Imager Download

Raspberry Pi Imager 2.x introduced a redesigned setup wizard and improved customization options. oai_citation:3‡Raspberry Pi

Step 2: Flash Raspberry Pi OS

Install Raspberry Pi OS

1. Insert your microSD card or SSD into your computer.

2. Open Raspberry Pi Imager.

3. Select:

   • Your Raspberry Pi model
   • Operating system
   • Storage device

Recommended Operating System (2026)

Raspberry Pi OS Trixie (64-bit)

Current modern release based on Debian 13. oai_citation:4‡Raspberry Pi

Legacy Option

Bookworm remains available for compatibility with older projects and software. oai_citation:5‡Raspberry Pi

Configure Before Flashing

Raspberry Pi Imager allows preconfiguration of:

• Hostname
• Username/password
• Wi-Fi
• SSH
• Locale
• Timezone
• Raspberry Pi Connect remote access

This avoids needing a monitor for initial setup. oai_citation:6‡Raspberry Pi

Write the Image

Click:

• Write

Wait for verification to complete, then safely eject the media.

Step 3: Assemble Your Raspberry Pi

Connect Components

1. Insert the microSD card or SSD.

2. Connect:

   • Monitor
   • Keyboard
   • Mouse
   • Ethernet (optional)

3. Connect power.

The Raspberry Pi will automatically boot.

Step 4: First Boot Setup

On first startup:

• Accept setup prompts
• Configure locale and keyboard
• Connect Wi-Fi
• Update software
• Change default password if prompted

Step 5: Configure Your Raspberry Pi

Update the System

Open Terminal and run:

sudo apt update && sudo apt full-upgrade -y

Security Changes in 2026

Recent Raspberry Pi OS releases disabled passwordless sudo by default for improved security. oai_citation:7‡9to5Linux

This means administrative commands now require your password.

Enable SSH

Run:

sudo raspi-config

Navigate to:

• Interface Options
• SSH
• Enable

Check System Information

uname -a

cat /etc/os-release

Docker and Home Server Setup

Raspberry Pi is widely used for self-hosted applications.

Install Docker

curl -fsSL https://get.docker.com | sh

Add your user to the Docker group:

sudo usermod -aG docker $USER

Then reboot:

sudo reboot

Common Docker Applications

Popular services include:

• Home Assistant
• Plex
• Jellyfin
• Pi-hole
• Homebridge
• Immich
• Nextcloud
• Portainer
• Nginx Proxy Manager
• Authentik

Recommended Storage Setup

For Docker and databases:

• Use SSD or NVMe instead of microSD
• Avoid heavy writes on cheap SD cards

Raspberry Pi Connect

Raspberry Pi Connect is now integrated into Raspberry Pi Imager and Raspberry Pi OS for remote access. oai_citation:8‡Raspberry Pi

It provides:

• Remote shell access
• Screen sharing
• Browser-based remote access

Without needing complex port forwarding.
