= Working with Variant Attributes

As explained in the section on <<variant_model.adoc#sec:variant-aware-matching,variant aware matching>>, attributes give semantics to variants and are used by Gradle's dependency management engine to select the best matching variant.

As a user of Gradle, attributes are often hidden as implementation details.
