Gradle provides multiple ways to inspect your build:

- Profile with build scans
- Local profile reports
- Low level profiling

== What is a build scan?

Everyone has to start somewhere, and if you're new to Gradle, this is where to begin.

To get started using Gradle:

The sole reason to use any build cache is to make builds faster.
But how much faster can you go when using the cache?
