+- What is Docker? Docker is a tool that helps you bundle up and use programs easily. It's like a box that holds all the things needed to run an app.
+- What is a Docker container? A Docker container is a small and self-contained package that has everything necessary to run a program. It's like a tiny computer that runs only one program.
+- What is a Docker image? A Docker image is a blueprint for creating a Docker container. It's like a recipe that tells Docker how to build a container.
+- What is Docker Compose? Docker Compose is a tool that makes it simple to manage and run multiple Docker containers together. It's like a manager that coordinates different containers for a group of apps.
