FireHydrant has two main ways to break your application into smaller pieces. Services are the smaller of the two. A service could be a microservice, your monorepo, or a library you maintain.
To create and manage services, click "Services" on the left navigation. Then click "New" on the right side of the page. Or, just click this link.
On the New page, enter in the name of the environment, and (optionally) a description.
You can also add labels to services so that you can search for them easier later.
