title: How can I add Spring Boot into an existing project?
body: <p>I am new to Spring and Java in general. I am working on a REST API and want to use Spring. I have read the Spring docs on <a href="https://spring.io/quickstart" rel="nofollow noreferrer">getting started with Spring</a> but most of them only talk about how to start a Spring project from scratch. I already have an existing Maven project and want to add Spring to that. Can anyone help with that?</p>
  <p>I'm using IntelliJ CE 2020.3 if that helps.</p>
