Whats good documentation for Gradle?

I use Gradle for my open source projects. I like its features, specifically the easy way to do multi project builds.

I struggled with the official documentation on the website. A common trap with technical docs: a lot of details on how things work internally and how you can configure the tool.

What I miss is: say you have goal X, like publishing your project on Maven Central, what are the exact recommended steps to do that? I dont want to become a Gradle expert, I want to get a job done.

I had to figure out a lot by googling, Stack Overflow and reading blogs.

What are your experiences with Gradle docs? Do you know good and reliable sources of information about Gradle?
