Before we get started with launching our application, which was created in the previous recipes, we need to install the envconsul utility.

Download the binary for your respective operating system from https://github.com/hashicorp/envconsul/releases and extract the executable to any directory of your choice, though it is better to put it somewhere that is in the PATH.

Once envconsul is extracted from the downloaded archive, we are ready to start using it so as to configure our application.
