# Introduction In this lab you will run a popular, free, lightweight container and explore the basics of how containers work, how the Docker Engine executes and isolates containers from each other. If you already have experience running containers and basic Docker commands you can probably skip this intro exercise.Concepts in this exercise: - Docker engine - Containers & images - Image registries and Docker Hub - Container isolationTips: Code snippets are shown in one of three ways throughout this environment: 1. Code that looks like `this` is sample code snippets that is usually part of an explanation. 2. Code that appears in box like the one below can be clicked on and it will automatically be typed in to the appropriate terminal window: ```bash uname -a ``` 3. Code appearing in windows like the one below is code that you should type in yourself. Usually there will be a unique ID or other bit your need to enter which we cannot supply. Items appearing in <> are the pieces you should substitute based on the instructions. ``` docker container start <container ID> ```
