+# Deployment Instructions for AWS EC2
+
+This guide will help you deploy the **WonderSheets** application to your EC2 instance using Docker.
+
+## Prerequisites
+
+1.  **AWS EC2 Instance**: A running instance (e.g., Amazon Linux 2 or Ubuntu).
+2.  **Security Group Rules**: Ensure your EC2 Security Group allows:
+    - **Inbound HTTP (Port 80)**: For the web interface.
+    - **Inbound SSH (Port 22)**: For you to connect.
+3.  **API Key**: Your Google Gemini API Key.
+
+## Step 1: Connect to your EC2 Instance
+
+Open your terminal and SSH into your server:
+
+```bash
+ssh -i /path/to/your-key.pem user@your-ec2-public-ip
+```
+
+## Step 2: Install Docker and Docker Compose (if not installed)
+
+**For Amazon Linux 2023 / Amazon Linux 2:**
+
+```bash
+sudo yum update -y
+sudo yum install -y docker
+sudo service docker start
+sudo usermod -a -G docker ec2-user
+# Logout and log back in to apply group changes
+exit
+# ssh again...
+```
+
+**Install Docker Compose:**
+
+```bash
+sudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
+sudo chmod +x /usr/local/bin/docker-compose
+```
+
+*(If you are using Ubuntu, use `sudo apt update && sudo apt install docker.io docker-compose -y`)*
+
+## Step 3: Get the Code
+
+You can either clone the repository or upload your files.
+
+**Option A: Git Clone (Recommended)**
+If your code is on Gitea/GitHub:
+
+```bash
+git clone <your-repo-url>
+cd wondersheets
+```
+
+**Option B: Upload Files**
+If you want to copy local files:
+```bash
+scp -i /path/to/key.pem -r . user@your-ec2-ip:~/wondersheets
+```
+
+## Step 4: Configure Environment
+
+Create a `.env` file in the project directory:
+
+```bash
+nano .env
+```
+
+Paste your API key:
+```
+GEMINI_API_KEY=your_actual_api_key_here
+```
+Save and exit (`Ctrl+O`, `Enter`, `Ctrl+X`).
+
+## Step 5: Start the Application
+
+Run the application in the background:
+
+```bash
+docker-compose up -d --build
+```
+
+## Step 6: Verify
+
+Open your browser and visit your EC2 Public IP:
+`http://your-ec2-public-ip/`
+
+The app should be running!
+
+---
+
+### Troubleshooting
+
+- **Check logs**: `docker-compose logs -f`
+- **Restart**: `docker-compose restart`
+- **Stop**: `docker-compose down`
