+# PWA Containerized Deployment
+
+This document provides step-by-step instructions to pull the source code and deploy the Progressive Web App (PWA) using Docker on a production server.
+
+## Prerequisites
+
+- **Git:** Installed on your production server.
+- **Docker:** Installed and running on your production server.
+- **Basic Knowledge:** Familiarity with the command line.
+
+## Steps
+
+### 1. Clone the Repository
+
+Log in to your production server and navigate to the directory where you want to store the project. Then run:
+
+```bash
+git clone https://gitea.virtonline.eu/2HoursProject/game-timer.git
+cd game-timer
+```
+
+### 2. Build the docker image
+
+From the repository root, run the following command to build your Docker image:
+
+```bash
+docker build -t 'game-timer:latest' .
+```
+
+### 3. Run the Docker Container
+
+Once the image is built, run the container on port 8080 with:
+
+```bash
+docker run -d -p 8080:80 --name game-timer-container game-timer:latest
+```
+
+### 4. Verify the Deployment
+
+Check if it's running:
+
+```bash
+docker ps
+```
+
+View logs (if needed):
+
+```bash
+docker logs game-timer-container
+```
+
+After running the container, open your web browser and navigate to:
+
+```bash
+http://localhost
+```
+
+### 5. Terminate
+
+To stop your running game-timer-container, use:
+
+```bash
+docker stop game-timer-container
+```
