This information is used to generate documentation for each Gradle version
on [docs.gradle.org](https://docs.gradle.org/).
The documentation is mostly implemented in Asciidoc
though we use GitHub-flavored Markdown for internal documentation too.

You can generate docs by running `./gradlew :docs:docs`.
This will build the whole documentation locally in [platforms/documentation](./platforms/documentation).
