+# Docker Web Application with MySQL and Nginx
+
+## Requirements
+- Docker
+- Docker Compose
+
+## Description
+This web application consists of two services:
+1. A **web service** using Nginx to serve static HTML files.
+2. A **database service** using MySQL, which persists its data in a Docker volume.
+
+## Docker Volumes and Networks
+- **Volume**: `db_data` - used to persist MySQL data.
+- **Network**: `app-network` - internal network for the services to communicate.
+
+## Configuration
+- **Nginx**: Serves static HTML files from the `/html` directory.
+- **MySQL**: Configured with `MYSQL_ROOT_PASSWORD` and a default database `mydb`.
+
+## How to Use
+
+### Preparing the app
+Run the following command to prepare the application:
+```bash
+./prepare-app.sh
+```
+
+### Starting the app
+To start the app, run:
+```bash
+./start-app.sh
+```
+
+The app will be available at `http://localhost:5000`.
+
+### Stopping the app
+To stop the app, run:
+```bash
+./stop-app.sh
+```
+
+### Removing the app
+To remove all resources related to the app, run:
+```bash
+./remove-app.sh
+```
+
+## Example usage
+
+```bash
+# Prepare the app
+./prepare-app.sh
+Preparing app...
+
+# Start the app
+./start-app.sh
+Running app ...
+The app is available at http://localhost:5000
+
+# Stop the app
+./stop-app.sh
+Stopping app...
+
+# Remove the app
+./remove-app.sh
+Removed app.
+```
