+# PM-RAG-ChatBot Setup Guide
+
+## Prerequisites
+
+### 1. Python 3.8 or higher
+Make sure Python is installed on your system.
+
+### 2. System Dependencies (for PDF processing)
+
+#### Windows:
+- **Poppler** (for PDF to image conversion):
+  - Download from: https://github.com/oschwartz10612/poppler-windows/releases/
+  - Extract and add `bin` folder to your system PATH
+  - Or set `POPPLER_PATH` environment variable to the `bin` folder
+
+- **Tesseract OCR** (optional, for OCR):
+  - Download from: https://github.com/UB-Mannheim/tesseract/wiki
+  - Install and add to PATH
+
+#### Alternative (using conda):
+```bash
+conda install -c conda-forge poppler tesseract
+```
+
+### 3. API Keys
+
+Create a `.env` file in the project root with:
+
+```env
+ANTHROPIC_API_KEY=your_anthropic_api_key_here
+POPPLER_PATH=C:\path\to\poppler\bin  # Optional, if not in PATH
+CLAUDE_VISION_MODEL=claude-sonnet-4-5-20250929  # Optional, defaults to this
+```
+
+**Get your Anthropic API key:**
+- Sign up at https://console.anthropic.com/
+- Create an API key
+- Add it to your `.env` file
+
+## Installation Steps
+
+### 1. Navigate to the project directory
+```bash
+cd PM-RAG-ChatBot
+```
+
+### 2. Create a virtual environment (recommended)
+```bash
+python -m venv venv
+```
+
+### 3. Activate the virtual environment
+
+**Windows (PowerShell):**
+```powershell
+.\venv\Scripts\Activate.ps1
+```
+
+**Windows (Command Prompt):**
+```cmd
+venv\Scripts\activate.bat
+```
+
+### 4. Install Python dependencies
+```bash
+pip install -r requirements.txt
+```
+
+**Note:** Some packages may require additional setup:
+- `camelot-py[cv]` requires `ghostscript` and `tcl-tk` on some systems
+- `spacy` may need a language model: `python -m spacy download en_core_web_sm`
+
+### 5. Install Spacy language model (if needed)
+```bash
+python -m spacy download en_core_web_sm
+```
+
+## Running the Application
+
+### Option 1: Web Interface (Chainlit) - Recommended
+```bash
+chainlit run app.py
+```
+
+This will start a web server (usually at http://localhost:8000)
+
+### Option 2: Command Line Interface
+```bash
+python main_final.py
+```
+
+## Project Structure
+
+- `app.py` - Main Chainlit web application
+- `main_final.py` - Command-line interface
+- `srd_engine_v2.py` - Main RAG engine with knowledge base
+- `srd_engine_final.py` - Core SRD chatbot engine
+- `db.py` - SQLite database models
+- `requirements.txt` - Python dependencies
+
+## Features
+
+- Upload SRD PDF documents
+- Process diagrams with vision models (Qwen2-VL and/or Claude Vision)
+- Chat interface for querying documents
+- Persistent chat history
+- Learning from user feedback
+
+## Troubleshooting
+
+1. **"ghostscript not found" error:**
+   - Install Ghostscript: https://www.ghostscript.com/download/gsdnld.html
+
+2. **"Poppler not found" error:**
+   - Make sure Poppler is installed and in PATH, or set `POPPLER_PATH` in `.env`
+
+3. **"ANTHROPIC_API_KEY not set" error:**
+   - Create a `.env` file with your API key
+
+4. **Import errors:**
+   - Make sure virtual environment is activated
+   - Reinstall requirements: `pip install -r requirements.txt --force-reinstall`
