+# Device Customization Setup Guide
+
+This guide documents the manual steps required to configure your Bose SoundTouch device for customization using the SoundCork approach.
+
+Based on: https://github.com/deborahgu/soundcork
+
+## Overview
+
+SoundCork allows you to customize your SoundTouch device by intercepting and modifying its firmware update process. This requires specific manual configuration steps to prepare your device.
+
+## Prerequisites
+
+- Bose SoundTouch device
+- Network access to device
+- Administrative access to your router/network
+
+## Configuration Steps
+
+### Step 1: Prepare USB Drive
+- Insert USB stick into computer
+- Create remote services file: `touch /path/to/mounted/usb/root-directory/remote_services`
+
+### Step 2: Connect to Device
+- Insert USB stick into SoundTouch 20 device
+- Restart device (unplug power, plug it back in)
+
+### Step 3: Access Device via SSH or Telnet
+
+After the restart, remote access is enabled.
+
+#### Option A: SSH
+- SSH access: `ssh -oHostKeyAlgorithms=ssh-rsa root@<device-ip>`
+- Device will show network interfaces and system info
+- No password required for root access
+
+Example output:
+```text
+gesellix@Mac Bose-SoundTouch % ssh -oHostKeyAlgorithms=ssh-rsa root@<device-ip>

+
+#### Option B: Telnet via Docker
+If you don't have a telnet client installed, you can use Docker:
+```bash
+docker run --rm -it alpine:edge ash -c 'apk add -U inetutils-telnet && telnet <device-ip> 23'
+```
+
+Example output:
+```text
+Trying <device-ip>...
+Connected to <device-ip>.
+Escape character is '^]'.
