-# WebApp Docker Deployment
+# 🧠 Typing Speed & RSI Awareness Game - Kubernetes Deployment
 
-# Requirements -
+This project showcases a web-based **Typing Speed & RSI Awareness Game** deployed on a Kubernetes cluster. Although the game is a simple frontend app (HTML, CSS, JavaScript), the Kubernetes setup is fully compliant with deployment best practices and assignment requirements.
 
-Docker installed
+---
 
-Docker Compose (optional)
+## 🎮 Game Overview
 
-# Description -
-This application consists of a web service and a database service. The web service runs on an Apache server with PHP and connects to a MySQL database.
+The application is designed to:
+- Improve typing speed and accuracy.
+- Educate users on RSI (Repetitive Strain Injury) prevention.
+- Include real-time feedback and typing stats.
+- Encourage healthy typing habits with periodic stretch reminders.
 
-# Networks and Volumes -
-my_network: A bridge network for inter-container communication.
+---
 
-# mysql_data - 
+## 📁 Project Structure
 
-A volume to persist database data.
+ File/Folder        Description |
 
-# Container Configuration
-apache: Web service running Apache with PHP, exposes port 8080.
+| index.html`, `style.css`, `script.js` | Frontend game files |
+| Dockerfile`       | Builds Nginx image to serve the game |
+| prepare-app.sh`   | Prepares the environment and Docker image |
+| start-app.sh`     | Applies all Kubernetes resources |
+| stop-app.sh`      | Cleans up all Kubernetes resources |
+| namespace.yaml`   | Creates the `typing-game` namespace |
+| deployment.yaml`  | Deploys the frontend via Nginx |
+| service.yaml`     | Exposes frontend using NodePort |
+| pv-pvc.yaml`      | Defines persistent volume and claim |
+| statefulset.yaml` | Dummy backend with StatefulSet + PVC |
+| 
 
-# mysql - 
+---
 
-MySQL database service using the official MySQL image, exposes port 3306.
+##  How to Run
 
-# Instructions
+### Step 1: Prepare the Application
 
-Prepare the application: ./prepare-app.sh
+```bash
+./prepare-app.sh
+```
 
-Start the application: ./start-app.sh
+- Builds the Docker image: `typing-game`
+- Saves it as a `.tar` for loading on cluster nodes
+- Prepares persistent storage
 
-Stop the application: ./stop-app.sh
+---
 
-Remove the application: ./remove-app.sh
+### Step 2: Deploy the Application
+
+```bash
+./start-app.sh
+```
+
+This applies:
+- Namespace
+- Deployment
+- Service
+- StatefulSet
+- PersistentVolume + PersistentVolumeClaim
+
+---
+
+### Step 3: Access the App
+
+Open in your browser:
+
+```
+http://<your-node-ip>:30007
+```
+
+> Replace `<your-node-ip>` with the external IP of your Kubernetes node.
+
+---
+
+### Step 4: Clean Up
+
+```bash
+./stop-app.sh
+```
+
+This deletes all Kubernetes resources created by this project.
+
+---
+
+## ✅ Assignment Requirements Fulfilled
+
+### 1. Namespace
+**Requirement:** All objects must belong to a custom namespace.  
+**You Did:** Defined `typing-game` in `namespace.yaml`, and referenced it in all other files.
+
+### 2. Deployment
+**Requirement:** Deploy your web application.  
+**You Did:** Used `deployment.yaml` to deploy your frontend game using Nginx.
+
+### 3. StatefulSet + PersistentVolume + PersistentVolumeClaim
+**Requirement:** Demonstrate persistent storage via a StatefulSet.  
+**You Did:**
+- Used `statefulset.yaml` with Alpine Linux writing logs to `/data/log.txt`.
+- Mounted `/data` using a PVC created from `pv-pvc.yaml`.
+
+### 4. Service
+**Requirement:** Expose your app.  
+**You Did:** Used a `NodePort` service in `service.yaml` on port `30007`.
+
+### 5. start-app.sh
+**Requirement:** Script to create all objects.  
+**You Did:** Automated creation of namespace, Deployment, Service, StatefulSet, PV/PVC.
+
+### 6. stop-app.sh
+**Requirement:** Script to delete all objects.  
+**You Did:** Cleanly removes all created Kubernetes objects.
+
+### 7. prepare-app.sh
+**Requirement:** Prepares the environment.  
+**You Did:** Builds and saves Docker image, prepares persistent volume.
+
+### 8. Dockerfile
+**Requirement:** Provide necessary container files.  
+**You Did:** Dockerfile builds a custom Nginx image that serves your HTML/JS/CSS game files.
 
-# Accessing the Application
 
-Open a web browser and navigate to http://localhost:8080.
