+# ChatDocs AI
+RAG-based generative AI application enabling interactive communication with PDF documents. Developed using Streamlit and Groq AI Inference technology.
+
+# Supported Models
+This application makes use of following LLMs:
+  - Chat Models — Groq AI:
+      - Llama3-8b-8192
+      - Llama3-70b-8192
+      - Mixtral-8x7b-32768
+      - Gemma-7b-it
+  - Embeddings -- OpenAI
+      - Text-embedding-ada-002-v2
+    
+# System Requirements
+- Python 3.9 or later (earlier versions are not compatible).
+
+# Installation
+1. Fork the repository and then follow the steps given below!
+   
+2. Clone the repository
+```bash
+git clone https://github.com/<your-username>/ML-Nexus.git
+cd ML-Nexus/Generative Models/ChatDocs-AI
+```
+3. Create and activate a virtual environment:
+```bash
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+```
+4. Install required Python packages:
