# What is Docker

Docker is a tool that lets you run software in a safe, isolated container on your computer - like running an app in a little box that keeps it separate from everything else.

Think of it like this:

* You can run the Equilibria node software without installing it directly on your computer
* It's like downloading an app that runs in its own space, separate from your other programs
* Docker handles all the technical stuff for you - you just need to install Docker and copy-paste a command
* It's free, safe, and used by millions of people
