Now to install just this component: ```sh $ composer require google/longrunning ``` This component supports both REST over HTTP/1.1 and gRPC.

Once authenticated, you'll be ready to start making requests. ### Version This component is considered beta. As such, it should be expected to be mostly stable and we're working towards a release candidate. We will address issues and requests with a higher priority. ### Next Steps 1.
