+# Docker Setup and Running Instructions
+
+This document provides instructions on how to set up and run the application using Docker and Docker Compose.
+
+## Prerequisites
+
+Before you begin, ensure you have the following installed on your system:
+
+*   Docker: Follow the official installation guide for your operating system.
+*   Docker Compose: Follow the official installation guide for your operating system.
+
+## Setup
+
+1.  **Environment Variables:**
+    Create a `.env` file in the same directory as the `docker-compose.yaml` file. This file will contain the environment variables required by the application. Add the following content to the `.env` file:
+
+    ```env
+    KITE_API_KEY=YOUR_KITE_API_KEY
+    KITE_API_SECRET=YOUR_KITE_API_SECRET
+    APP_MODE=sse
+    APP_HOST=0.0.0.0
+    APP_PORT=8080
+    ```
+
+    **Replace `YOUR_KITE_API_KEY` and `YOUR_KITE_API_SECRET` with your actual Kite API credentials.**
+
+2.  **Dockerfile:**
+    Ensure a `Dockerfile` exists in the same directory as the `docker-compose.yaml` file. This file contains the instructions to build the Docker image.
+
+## Running the Application
+
+1.  **Build and Run:**
+    Open your terminal, navigate to the directory containing the `docker-compose.yaml` and `.env` files, and run the following command:
+
+    ```bash
+    docker compose up --build -d
+    ```
+
+    *   `--build`: This flag tells Docker Compose to build the images before starting the containers.
+    *   `-d`: This flag runs the containers in detached mode (in the background).
+
+2.  **Stopping the Application:**
+    To stop the running containers, use the following command in the same directory:
+
+    ```bash
+    docker compose down
+    ```
+
+## Accessing the Application
+
+The application should be accessible on `http://localhost:8080` (or the IP address of your server if not running locally) after the containers are up and running.
