+## Handling binary dependencies
+AndroidX uses git to store all the binary Gradle dependencies. They are stored in `prebuilts/androidx/internal` and `prebuilts/androidx/external` directories in your checkout. All the dependencies in these directories are also available from `google()`, `jcenter()`, or `mavenCentral()`. We store copies of these dependencies to have hermetic builds. You can pull in [a new dependency using our importMaven tool](development/importMaven/README.md).
