+# Pure JavaScript gRPC Client
+
+**Note: This is an beta-level release. Some APIs may not yet be present and there may be bugs. Please report any that you encounter**
+
+## Installation
+
+Node 10 is recommended. The exact set of compatible Node versions can be found in the `engines` field of the `package.json` file.
+
+```sh
+npm install @grpc/grpc-js
+```
+
+## Features
+
+ - Unary and streaming calls
+ - Cancellation
+ - Deadlines
+ - TLS channel credentials
+ - Call credentials (for auth)
+ - Simple reconnection
+ - Channel API
+
+This library does not directly handle `.proto` files. To use `.proto` files with this library we recommend using the `@grpc/proto-loader` package.
+
+## Some Notes on API Guarantees
+
+The public API of this library follows semantic versioning, with some caveats:
+
+ - Some methods are prefixed with an underscore. These methods are internal and should not be considered part of the public API.
+ - The class `Call` is only exposed due to limitations of TypeScript. It should not be considered part of the public API.
+ - In general, any API that is exposed by this library but is not exposed by the `grpc` library is likely an error and should not be considered part of the public API.
