-## Spring Framework
-The Spring Framework provides a comprehensive programming and configuration
-model for modern Java-based enterprise applications -- on any kind of deployment
-platform. A key element of Spring is infrastructural support at the application
-level: Spring focuses on the "plumbing" of enterprise applications so that teams
-can focus on application-level business logic, without unnecessary ties to
-specific deployment environments.
-
-The framework also serves as the foundation for [Spring Integration][], [Spring Batch][]
-and the rest of the Spring [family of projects][]. Browse the repositories under
-the [Spring organization][] on GitHub for a full list.
