+# Setup
+
+This guide provides instructions on how to set up and run the application.
+
+## Prerequisites
+
+Ensure you have the following installed on your system:
+- **Docker**: Install Docker from [docker.com](https://www.docker.com/get-started)
+- **Docker Compose**: Docker Compose is included with Docker Desktop (for macOS/Windows) or can be installed separately on Linux.
+
+## Steps to Set Up the Application
+
+### 1. Clone the Repository
+
+First, clone the repository to your local machine:
+
+```bash
+git clone https://github.com/username/repository.git
+cd repository
+```
+
+
+### 2. Create a `.env` File
+
+Before running the application, create a `.env` file in the root directory and add the required environment variables:
+
+```bash
+touch .env
+```
+
+Then, open the `.env` file and add the following:
+
+```ini
+# Environment Variables
+VALID_API_KEY=testtest-api-key-12345
+VALID_APP_ID=app1
+```
+
+This ensures that the application uses secure API keys and app IDs.
+
+### 3. Run the Application with Docker Compose
+
+Once you have the repository cloned, you can easily set up and run the application using Docker Compose. Simply execute the following command:
+
+```bash
+docker-compose up --build
+```
+
+This command will build the Docker image and start the Flask application in a container. By default, the application will be accessible at `http://localhost:5000`.
+
+### 4. Health Check
+
+You can check if the Flask application is running by accessing the `/health` endpoint. To perform a health check, run the following command:
+
+```bash
+curl http://localhost:7200/health
+```
+
+If the application is running properly, you should receive a response similar to this:
+
+```json
+{
+  "status": "ok"
+}
+```
+
+### 5. Stop the Application
+
+To stop the application, use:
+
+```bash
+docker-compose down
+```
+
+This will stop and remove the containers created by Docker Compose.
