# Tutorial: Setting Up a Self-Hosted BTCPay Server with Umbrel

Setting up a BTCPay Server for your business or personal use can seem daunting, but with Umbrel OS, it's straightforward and doesn't require any coding. Follow these steps to get your BTCPay Server up and running in no time.

**Note:** Umbrel OS and all the apps mentioned in this tutorial are free and open-source. You can find all the code on GitHub.

## Prerequisites

Before you begin, ensure you have the following:

1. A Raspberry Pi 4/5 ( 8GB recommended)
2. A microSD card (32GB or larger)
3. A reliable internet connection
4. An external SSD (recommended for blockchain storage)
5. Basic knowledge of how to connect and power up your Raspberry Pi

## Step 1: Install Umbrel OS

### 1.1 Download Umbrel OS

- Go to the [Umbrel website](https://getumbrel.com) and download the latest Umbrel OS image for Raspberry Pi. Umbrel OS is free and open-source. You can find the source code on [GitHub](https://github.com/getumbrel/umbrel).

### 1.2 Flash Umbrel OS to Your microSD Card

- Use a tool like [Balena Etcher](https://www.balena.io/etcher/) to flash the Umbrel OS image onto your microSD card.
- Insert your microSD card into your computer.
- Open Balena Etcher.
- Select the Umbrel OS image you downloaded.
- Select your microSD card as the target.
- Click "Flash" and wait for the process to complete.

### 1.3 Setup Umbrel
