### How Gradle Works

We have [a series of blog](https://blog.gradle.org/how-gradle-works-1) that explains how Gradle works.
This may help you better understand and contribute to Gradle.

### Debugging Gradle

You can debug Gradle by adding `-Dorg.gradle.debug=true` to the command-line. Gradle will wait for you to attach a debugger at `localhost:5005` by default.
