  -== Update to the latest Gradle version
  +=== Gradle
   
   The Gradle team continuously improves the performance of Gradle builds.
   If you’re using an old version of Gradle, you’re missing out on the benefits of that work.
   Keeping up with Gradle version upgrades is low risk because the Gradle team ensures backwards compatibility between minor versions of Gradle.
   Staying up-to-date also makes transitioning to the next major version easier, since you'll get early deprecation warnings.
   
  -== Upgrade to the latest Java version
  +=== Java

  Eliminate these slow or unexpected downloads by switching to a different repository or dependency.
  
  == Create builds for specific developer workflows
  
  The fastest task is one that doesn’t execute.
  If you can find ways to skip tasks you don’t need to run, you’ll end up with a faster build overall.
  
  If your build includes multiple subprojects, create tasks to build those subprojects
  independently. This helps you get the most out of caching, since a change to one
