Be aware these are very technical descriptions of the decisions, and you might find the documentation below more useful as an introduction to the internals of Gradle.

## Platform architecture

Gradle is arranged into several coarse-grained components called "platforms".
Each platform provides support for some kind of automation, such as building JVM software or building Gradle plugins.
Most platforms typically build on the features of other platforms.
