+Setting up the described application involves several steps, including preparing the environment, configuring the backend and frontend, setting up Docker, and running the application. Here's a step-by-step guide to create the setup:
+
+### Step 1: Clone the Repository
+
+First, clone the repository to your local machine.
+
+```bash
+git clone https://github.com/JoeySoprano420/UnifiedApp.git
+cd UnifiedApp
+```
+
+### Step 2: Backend Setup
+
+Navigate to the `backend` directory and install the necessary dependencies.
+
+```bash
+cd backend
+npm install
+```
+
+Create a `config` directory inside the `backend` directory and add a `default.json` file for configuration.
+
+```bash
+mkdir config
+nano config/default.json
+```
+
+Add the following configuration to `default.json`:
+
+```json
+{
+  "PORT": 5000,
+  "mongoURI": "your_mongodb_connection_string",
+  "jwtSecret": "your_jwt_secret"
+}
+```
+
+### Step 3: Frontend Setup
+
+Navigate to the `frontend` directory and install the necessary dependencies.
+
+```bash
+cd ../frontend
+npm install
+```
+
+Create a `.env` file in the `frontend` directory and add the following environment variables:
+
+```env
+REACT_APP_API_URL=http://localhost:5000/api
+```
+
+### Step 4: Docker Setup
+
+Create a `Dockerfile` in the root directory:
+
+```bash
+nano Dockerfile
+```
+
+Add the following content to the `Dockerfile`:
+
+```dockerfile
+# Backend
+FROM node:14-alpine AS backend
+WORKDIR /app
+COPY backend/package*.json ./
+RUN npm install
+COPY backend/ .
+CMD ["node", "app.js"]
+
+# Frontend
+FROM node:14-alpine AS frontend
+WORKDIR /app
+COPY frontend/package*.json ./
+RUN npm install
+COPY frontend/ .
+RUN npm run build
+
+# Final Stage
+FROM nginx:alpine
+COPY --from=frontend /app/build /usr/share/nginx/html
+COPY nginx.conf /etc/nginx/nginx.conf
+```
+
+Create a `docker-compose.yml` file in the root directory:
+
+```bash
+nano docker-compose.yml
+```
+
+Add the following content to `docker-compose.yml`:
+
+```yaml
+version: '3'
+services:
+  backend:
+    build:
+      context: .
+      dockerfile: Dockerfile
+      target: backend
+    ports:
+      - "5000:5000"
+    environment:
+      - NODE_ENV=production
+
+  frontend:
+    build:
+      context: .
+      dockerfile: Dockerfile
+      target: frontend
+    ports:
+      - "3000:80"
+    environment:
+      - NODE_ENV=production
+```
+
+Create a `nginx.conf` file in the root directory:
+
+```bash
+nano nginx.conf
+```
+
+Add the following content to `nginx.conf`:
+
+```nginx
+server {
+    listen 80;
+
+    location / {
+        root /usr/share/nginx/html;
+        index index.html index.htm;
+        try_files $uri $uri/ /index.html;
+    }
+
+    location /api {
+        proxy_pass http://backend:5000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+}
+```
+
+### Step 5: Deployment Script
+
+Create a `scripts` directory and a `deploy.sh` script:
+
+```bash
+mkdir scripts
+nano scripts/deploy.sh
+```
+
+Add the following content to `deploy.sh`:
+
+```bash
+#!/bin/bash
+
+# Pull latest changes
+git pull
+
+# Build and start containers
+docker-compose up --build -d
+
+# Remove unused images
+docker image prune -f
+```
+
+Make the script executable:
+
+```bash
+chmod +x scripts/deploy.sh
+```
+
+### Step 6: Run the Application
+
+Run the deployment script to build and start the application:
+
+```bash
+./scripts/deploy.sh
+```
+
+### Step 7: Access the Application
+
+Once the containers are up and running, you can access the frontend at `http://localhost:3000` and the backend API at `http://localhost:5000/api`.
+
+### Step 8: Additional Configuration (Optional)
+
+#### Configure MongoDB
+
+Ensure you have MongoDB running and replace the `mongoURI` in the `default.json` file with your MongoDB connection string.
+
+#### Configure Environment Variables
+
+If you have any additional environment variables, configure them in the `.env` file for the frontend and the `default.json` for the backend.
+
+#### Add SSL/TLS (Optional)
+
+For production environments, consider adding SSL/TLS to secure the connections. You can use a reverse proxy like Nginx with Let's Encrypt to achieve this.

+This setup guide covers the basic configuration and deployment of the unified application. For a production environment, additional steps such as setting up CI/CD pipelines, monitoring, logging, and scaling might be necessary.
