-### Building and Running the Application
+## Running the Application
 
-### Build and Start Containers
+Before proceeding, you’ll need to have the example configuration files. These files—example.docker-compose.yml and example.env—are included in the repository. You can download them by cloning the entire repository:
 
-1. From the project root, run:
-`docker-compose up --build -d`
-This command will build the Docker image, start the container in detached mode, and mount the persistent volume at `/data` for the SQLite database.
+```
+git clone <https://github.com/tmdinosaurcenter/kiosk-guestbook.git>
+cd kiosk-guestbook
+```
 
-2. Access the Application:
-Open a web browser and navigate to `http://<your-server-ip>:8000` (or the port specified in your .env file).
+If you don’t wish to clone the entire repo, you can also download the two files individually from GitHub. Once you have them, follow the steps below.
 
-### Deployment with Docker Compose
+### Method 1: Using Docker on the CLI
 
-The `docker-compose.yml` is configured to:
+1. Copy Example Files:
+From the project root, copy the example files:
 
-- Build the image from the Dockerfile.
-- Expose the service on the specified port.
-- Mount a volume (named `guestbook_data`) at `/data` to persist your database.
-- Load environment variables from the `.env` file
+```
+cp example.docker-compose.yml docker-compose.yml
+cp example.env .env
+```
 
-### Logging and Monitoring
+2. **Edit the `.env` File (Optional):**
+
+Modify `.env` to customize settings such as `SITE_TITLE`, `LOGO_URL`, `PORT`, etc.
+
+3. **Start the Application**
+
+Run the following command to pull (or use) the pre-built image and start the container:
+
+`docker-compose up -d`
+
+This command starts the container in detached mode, mounts the persistent volume for the SQLite database, and uses your environment variable settings.
+
+4. **Access the Application:**
