   Enable and start Docker:

   systemctl enable docker
   systemctl start docker

Docker Installation (if applicable)

If your software supports Docker, follow these steps to set it up:

1. Pull the Docker Image

   docker pull your-software-image

2. Run the Docker Container

   docker run -d --name your-container-name your-software-image

Configuration
