-== Modules
-
-There are several modules in Spring Boot. Here is a quick overview:
-
-
-
-=== spring-boot
-
-The main library providing features that support the other parts of Spring Boot. These include:
-
-* The `SpringApplication` class, providing static convenience methods that can be used to write a stand-alone Spring Application.
-  Its sole job is to create and refresh an appropriate Spring `ApplicationContext`.
-* Embedded web applications with a choice of container (Tomcat, Jetty).
-* First-class externalized configuration support.
-* Convenience `ApplicationContext` initializers, including support for sensible logging defaults.
-
-
-
-=== spring-boot-autoconfigure
-
-Spring Boot can configure large parts of typical applications based on the content of their classpath.
-A single `@EnableAutoConfiguration` annotation triggers auto-configuration of the Spring context.
-
-Auto-configuration attempts to deduce which beans a user might need. For example, if `HSQLDB` is on the classpath, and the user has not configured any database connections, then they probably want an in-memory database to be defined.
-Auto-configuration will always back away as the user starts to define their own beans.
-
-
-
-=== spring-boot-starters
-
-Starters are a set of convenient dependency descriptors that you can include in your application.
-You get a one-stop shop for all the Spring and related technology you need without having to hunt through sample code and copy-paste loads of dependency descriptors.
-For example, if you want to get started using Spring and JPA for database access, include the `spring-boot-starter-data-jpa` dependency in your project, and you are good to go.
-
-
-
-=== spring-boot-actuator
-
-Actuator endpoints let you monitor and interact with your application.
-Spring Boot Actuator provides the infrastructure required for actuator endpoints.
-It contains annotation support for actuator endpoints.
-This module provides many endpoints, including the `HealthEndpoint`, `EnvironmentEndpoint`, `BeansEndpoint`, and many more.
-
-
-
-=== spring-boot-actuator-autoconfigure
-
-This provides auto-configuration for actuator endpoints based on the content of the classpath and a set of properties.
-For instance, if Micrometer is on the classpath, it will auto-configure the `MetricsEndpoint`.
-It contains configuration to expose endpoints over HTTP or JMX.
-Just like Spring Boot AutoConfigure, this will back away as the user starts to define their own beans.
-
-
-
-=== spring-boot-test
-
-This module contains core items and annotations that can be helpful when testing your application.
-
-
-
-=== spring-boot-test-autoconfigure
-
-Like other Spring Boot auto-configuration modules, spring-boot-test-autoconfigure provides auto-configuration for tests based on the classpath.
-It includes many annotations that can automatically configure a slice of your application that needs to be tested.
-
-
-
-=== spring-boot-loader
-
-Spring Boot Loader provides the secret sauce that allows you to build a single jar file that can be launched using `java -jar`.
-Generally, you will not need to use `spring-boot-loader` directly but work with the link:spring-boot-project/spring-boot-tools/spring-boot-gradle-plugin[Gradle] or link:spring-boot-project/spring-boot-tools/spring-boot-maven-plugin[Maven] plugin instead.
-
-
-
-=== spring-boot-devtools
-
-The spring-boot-devtools module provides additional development-time features, such as automatic restarts, for a smoother application development experience.
-Developer tools are automatically disabled when running a fully packaged application.
