+
+WeChatExporter is a specialized macOS application designed to export and preserve WeChat chat records without requiring device jailbreaking. The tool enables users to backup and review their chat history comprehensively, supporting multiple media types directly on their computer.
+
+### Key Features
+- Export chat records from iOS devices
+- Support for multiple message types:
+  - Text messages
+  - Voice recordings
+  - Images
+  - Videos
+- Preserve chat history across different time periods
+- User-friendly two-step export and review process
+
+### Core Capabilities
+The application provides a seamless solution for users who want to:
+- Create personal chat record backups
+- Review historical conversations
+- Preserve important communication memories
+- Export chat data without risking data loss
+
+### Technical Approach
+- Built using Node.js
+- Frontend framework: AngularJS
+- Platform support: macOS (with potential for future cross-platform expansion)
+- Data parsing through SQLite database interaction
+
+### Unique Benefits
+- No device jailbreaking required
+- Intuitive interface for data export and browsing
+- Preserves complete conversation context
+- Supports selective date range exports
+
+## Getting Started, Installation, and Setup
+
+### Prerequisites
+
+Before getting started, ensure you have the following installed:
+- Node.js (version 8.11.3 or 10.16.3 recommended)
+- NW.js (version 0.32.1 or 0.40.1)
+- macOS (primary supported platform)
+- Xcode (for building dependencies)
+
+### Quick Start
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/tsycnh/WeChatExporter
+   cd WeChatExporter/development
+   ```
+
+2. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+3. Compile SQLite3 for NW.js:
+   ```bash
+   # Install node-gyp
+   sudo npm install -g node-gyp
+
+   # Compile sqlite3 (example for NW.js v0.40.1, 64-bit)
+   npm install sqlite3 --build-from-source --runtime=node-webkit --target_arch=x64 --target=0.40.1
+   ```
+
+### Data Preparation
+
+#### iOS Data Export
+1. Use iTunes to backup your entire iPhone device (ensure backup is NOT encrypted)
+2. Use third-party software like iMazing to export the Documents folder containing WeChat backup data
+
+### Running the Application
+
+1. Start the application:
+   ```bash
+   /path/to/nwjs.app/Contents/MacOS/nwjs .
+   ```
+
+### Important Notes
+
+- Currently supports iOS systems primarily
+- Application runs only on macOS
+- Android and Windows users can migrate chat records to iPad for export
+
+### Troubleshooting
+
+- Verify NW.js and Node.js versions match
+- Check runtime logs via [Tools] -> [Export Runtime Logs]
+- Ensure all dependencies are correctly compiled for your specific platform

+   
+   # Navigate to the project directory
+   cd WeChatExporter/development
+   
+   # Install dependencies
+   npm install
+   ```
+
+3. Compile SQLite3 (for macOS)
+   ```bash
+   # Install Xcode from App Store
+   sudo npm install -g node-gyp
+   
+   # Compile sqlite3 (adjust target based on your nwjs version)
+   npm install sqlite3 --build-from-source --runtime=node-webkit --target_arch=x64 --target=0.40.1
+   ```
+
+### Running the Exporter
+
+1. Start the Application
+   ```bash
+   # Run with nwjs (replace path with your nwjs installation)
+   /path/to/nw/nwjs.app/Contents/MacOS/nwjs .
+   ```
+
+2. Export Workflow
+   - Click "Start Original Data Analysis"
+   - Select the WeChat account
+   - Choose chat partner (default shows chats with >100 messages)
