+- `26`, `latest` [Dockerfile](https://github.com/Codeminer42/docker-ci-android/blob/master/26/Dockerfile)
+
+## Contributing
+
+`Dockerfiles` are stored under folders for each version.
+
+For updating the images, just open a _pull request_ with
+the new `Dockerfile` version and, after accepted, Docker
+Hub will build automatically after a few minutes.
+
+The images should setup an environment that is widely used,
+please don't install dependencies that are specific to a
+project. It's also good to have a pattern and all images
+support the same things.
