+# Installation Guide for Qwen Code with Source Tracking
+
+This guide describes how to install Node.js and Qwen Code with source information tracking.
+
+## Script: install-qwen-with-source.sh
+
+The script automates the installation of Node.js (if not present or below version 20) and Qwen Code, while capturing and storing the installation source information.
+
+### Features:
+- Checks for existing Node.js installation and version
+- Installs Node.js 20+ if needed using NVM
+- Installs Qwen Code globally with source information
+- Stores the source information in the ~/.qwen/source.json file
+
+### Usage:
+
+```bash
+# Install with a specific source
+./install-qwen-with-source.sh --source github
+
+# Install with internal source
+./install-qwen-with-source.sh -s internal
+
+# Show help
+./install-qwen-with-source.sh --help
+```
+
+### How it Works:
+
+1. The script accepts a `--source` parameter to specify where Qwen Code is being installed from
+2. It installs Node.js if needed
+3. It installs Qwen Code globally
+4. It creates `~/.qwen/source.json` with the specified source information
+5. The postinstall script validates and ensures proper formatting of the source.json file
+6. The source information is stored separately in `~/.qwen/source.json`
+
+### Prerequisites:
+- curl (for NVM installation and script download)
+- bash-compatible shell
+
+### Notes:
+- The script requires internet access to download Node.js and Qwen Code
+- Administrative privileges may be required for global npm installation
+- The installation source is stored locally and used for tracking purposes
+
+### Remote Execution:
+You can also run the script directly from a remote location using curl:
+
+```bash
+# Download and execute the script with a source parameter
+curl -fsSL https://your-domain.com/install-qwen-with-source.sh | bash -s -- --source github
+
+# Or download the script first, then execute
+curl -fsSL https://your-domain.com/install-qwen-with-source.sh -o install-qwen.sh
+chmod +x install-qwen.sh
+./install-qwen.sh --source github
+```
+
+Note: Replace `https://your-domain.com/install-qwen-with-source.sh` with the actual URL where the script is hosted.
+
+## Installation Source Feature
+
+### Overview
+This feature implements the ability to capture and store the installation source of the Qwen Code package.
+
+### How to Use
+
+To specify the installation source during npm install, you can use:
+
+#### Method 1: Using the Installation Script
+Use the provided installation script that handles Node.js installation and creates a source file:
+```bash
+./install-qwen-with-source.sh --source github
+```
+
+The script will:
+1. Install Node.js if needed
+2. Install Qwen Code globally
+3. Create `~/.qwen/source.json` with the specified source information
+4. The postinstall script validates the source.json file
+
+#### Default behavior
+If no source is specified, no source.json file will be created.
+
+### Storage Location
+The installation source is stored in a separate file at:
+- Unix/Linux/macOS: `~/.qwen/source.json`
+- Windows: `%USERPROFILE%\.qwen\source.json`
+
+The file contains:
+```json
+{
+  "source": "github"
+}
+```
+
+### Technical Details
+- The source information is stored as a separate JSON file
+- The feature integrates with the existing postinstall script for validation
+- The implementation does not modify the core settings system

 ## Installation Source Feature
 
 ### Overview
 
-This feature implements the ability to capture and store the installation source of the Qwen Code package.
-
-### How to Use
-
-To specify the installation source during npm install, you can use:
-
-#### Method 1: Using the Installation Script
-
-Use the provided installation script that handles Node.js installation and creates a source file:
-
-```bash
-./install-qwen-with-source.sh --source github
-```
-
-The script will:
-
-1. Install Node.js if needed
-2. Install Qwen Code globally
-3. Create `~/.qwen/source.json` with the specified source information
-4. The postinstall script validates the source.json file
-
-#### Default behavior
-
-If no source is specified, no source.json file will be created.
+This feature implements the ability to capture and store the installation source of the Qwen Code package. The source information is used for analytics and tracking purposes.
 
 ### Storage Location
 
 The installation source is stored in a separate file at:
 
-- Unix/Linux/macOS: `~/.qwen/source.json`
-- Windows: `%USERPROFILE%\.qwen\source.json`
+- **Unix/Linux/macOS**: `~/.qwen/source.json`
+- **Windows**: `$env:USERPROFILE\.qwen\source.json` (equivalent to `C:\Users\{username}\.qwen\source.json`)
 
-The file contains:
+### File Format
+
+The `source.json` file contains:
 
 ```json
 {
@@ -106,8 +122,101 @@ The file contains:
 }
 ```
 
-### Technical Details
+### How the Source Information is Used
+
+1. **Telemetry Tracking**: The source information is included in RUM (Real User Monitoring) telemetry logs
+2. **Analytics**: Helps understand how users are discovering and installing Qwen Code
+3. **Distribution Analysis**: Tracks which distribution channels are most popular
+
+### Technical Implementation
 
 - The source information is stored as a separate JSON file
-- The feature integrates with the existing postinstall script for validation
-- The implementation does not modify the core settings system
+- The `QwenLogger` class reads this file during telemetry initialization
+- The source is included in the `app.channel` field of the RUM payload
+- The implementation gracefully handles missing files, unknown values, and parsing errors
+
+### Verification
+
+After installation, you can verify the source information:
+
+**Linux/macOS:**
+
+```bash
+cat ~/.qwen/source.json
+```
+
+**Windows:**
+
+```powershell
+Get-Content $env:USERPROFILE\.qwen\source.json
+```
+
+## Manual Installation (Without Source Tracking)
+
+If you prefer not to use the installation scripts or don't want source tracking:
+
+### Prerequisites
+
+```bash
+# Node.js 20+
+curl -qL https://www.npmjs.com/install.sh | sh
+```
+
+### NPM Installation
+
+```bash
+npm install -g @qwen-code/qwen-code@latest
+```
+
+### Homebrew (macOS, Linux)
+
+```bash
+brew install qwen-code
+```
+
+## Troubleshooting
+
+### Script Execution Issues
+
+**Linux/macOS:**
+
+```bash
+# Make script executable
+chmod +x install-qwen-with-source.sh
+
+# Run with bash explicitly
+bash install-qwen-with-source.sh --source github
+```
+
+**Windows:**
+
+```powershell
+# Bypass execution policy
+powershell -ExecutionPolicy Bypass -File .\install-qwen-with-source.ps1 -Source github
+```
+
+### Node.js Installation Issues
+
+**Linux/macOS:**
+
+- Ensure NVM is installed: `curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash`
+- Restart your terminal or run: `source ~/.bashrc`
+
+**Windows:**
+
+- Install NVM for Windows from: https://github.com/coreybutler/nvm-windows/releases
+- After installation, run the script again
+
+### Permission Issues
+
+You may need administrative privileges for global npm installation:
+
+- **Linux/macOS**: Use `sudo` with npm
+- **Windows**: Run PowerShell as Administrator
+
+## Notes
+
+- The scripts require internet access to download Node.js and Qwen Code
+- Administrative privileges may be required for global npm installation
+- The installation source is stored locally and used for tracking purposes only
+- If the source file is missing or invalid, the application continues to work normally
