+# Google Routes API Client for Java
+
+Java idiomatic client for [Routes API][product-docs].
+
+[![Maven][maven-version-image]][maven-version-link]
+![Stability][stability-image]
+
+- [Product Documentation][product-docs]
+- [Client Library Documentation][javadocs]
+
+> Note: This client is a work-in-progress, and may occasionally
+> make backwards-incompatible changes.
+
+
+## Quickstart
+
+
+If you are using Maven, add this to your pom.xml file:
+
+
+```xml
+<dependency>
+  <groupId>com.google.maps</groupId>
+  <artifactId>google-maps-routing</artifactId>
+  <version>0.0.0</version>
+</dependency>
+```
+
+If you are using Gradle without BOM, add this to your dependencies:
+
+```Groovy
+implementation 'com.google.maps:google-maps-routing:0.0.0'
+```
+
+If you are using SBT, add this to your dependencies:
+
+```Scala
+libraryDependencies += "com.google.maps" % "google-maps-routing" % "0.0.0"
+```
+
+## Authentication
+
+See the [Authentication][authentication] section in the base directory's README.
+
+## Authorization
+
+The client application making API calls must be granted [authorization scopes][auth-scopes] required for the desired Routes API APIs, and the authenticated principal must have the [IAM role(s)][predefined-iam-roles] required to access GCP resources using the Routes API API calls.
+
+## Getting Started
+
+### Prerequisites
+
+You will need a [Google Cloud Platform Console][developer-console] project with the Routes API [API enabled][enable-api].
+You will need to [enable billing][enable-billing] to use Google Routes API.
+[Follow these instructions][create-project] to get your project set up. You will also need to set up the local development environment by
+[installing the Google Cloud SDK][cloud-sdk] and running the following commands in command line:
+`gcloud auth login` and `gcloud config set project [YOUR PROJECT ID]`.
+
+### Installation and setup
+
+You'll need to obtain the `google-maps-routing` library.  See the [Quickstart](#quickstart) section
+to add `google-maps-routing` as a dependency in your code.
+
+## About Routes API
+
+
+[Routes API][product-docs] Routes API is the next generation, performance optimized version of the existing Directions API and Distance Matrix API. It helps you find the ideal route from A to Z, calculates ETAs and distances for matrices of origin and destination locations, and also offers new features.
+
+See the [Routes API client library docs][javadocs] to learn how to
+use this Routes API Client Library.
+
+
+
+
+
+
+## Troubleshooting
+
+To get help, follow the instructions in the [shared Troubleshooting document][troubleshooting].
+
+## Transport
+
+Routes API uses gRPC for the transport layer.
+
+## Supported Java Versions
+
+Java 8 or above is required for using this client.
+
+Google's Java client libraries,
+[Google Cloud Client Libraries][cloudlibs]
+and
+[Google Cloud API Libraries][apilibs],
+follow the
+[Oracle Java SE support roadmap][oracle]
+(see the Oracle Java SE Product Releases section).
+
+### For new development
+
+In general, new feature development occurs with support for the lowest Java
+LTS version covered by  Oracle's Premier Support (which typically lasts 5 years
+from initial General Availability). If the minimum required JVM for a given
+library is changed, it is accompanied by a [semver][semver] major release.
+
+Java 11 and (in September 2021) Java 17 are the best choices for new
+development.
+
+### Keeping production systems current
+
+Google tests its client libraries with all current LTS versions covered by
+Oracle's Extended Support (which typically lasts 8 years from initial
+General Availability).
+
+#### Legacy support
+
+Google's client libraries support legacy versions of Java runtimes with long
+term stable libraries that don't receive feature updates on a best efforts basis
+as it may not be possible to backport all patches.
+
+Google provides updates on a best efforts basis to apps that continue to use
+Java 7, though apps might need to upgrade to current versions of the library
+that supports their JVM.
+
+#### Where to find specific information
+
+The latest versions and the supported Java versions are identified on
+the individual GitHub repository `github.com/GoogleAPIs/java-SERVICENAME`
+and on [google-cloud-java][g-c-j].
+
+## Versioning
+
+
+This library follows [Semantic Versioning](http://semver.org/).
+
+
+It is currently in major version zero (``0.y.z``), which means that anything may change at any time
+and the public API should not be considered stable.
+
+
+## Contributing

+Contributions to this library are always welcome and highly encouraged.

+See [CONTRIBUTING][contributing] for more information how to get started.
+
+Please note that this project is released with a Contributor Code of Conduct. By participating in
