+# gRPC Protobuf Loader
+
+A utility package for loading `.proto` files for use with gRPC, using the latest Protobuf.js package.
+
+## Installation
+
+```sh
+npm install @grpc/proto-loader
+```
+
+## Usage
+
+```js
+const protoLoader = require('@grpc/proto-loader');
+const grpcLibrary = require('grpc');
+// OR
+const grpcLibrary = require('@grpc/grpc-js');
+
+protoLoader.load(protoFileName, options).then(packageDefinition => {
+  const packageObject = grpcLibrary.loadPackageDefinition(packageDefinition);
+});
+// OR
+const packageDefinition = protoLoader.loadSync(protoFileName, options);
+const packageObject = grpcLibrary.loadPackageDefinition(packageDefinition);
+```
+
+The options parameter is an object that can have the following optional properties:
+
+| Field name | Valid values | Description
+|------------|--------------|------------
+| `keepCase` | `true` or `false` | Preserve field names. The default is to change them to camel case.
+| `longs` | `String` or `Number` | The type to use to represent `long` values. Defaults to a `Long` object type.
+| `enums` | `String` | The type to use to represent `enum` values. Defaults to the numeric value.
+| `bytes` | `Array` or `String` | The type to use to represent `bytes` values. Defaults to `Buffer`.
+| `defaults` | `true` or `false` | Set default values on output objects. Defaults to `false`.
+| `arrays` | `true` or `false` | Set empty arrays for missing array values even if `defaults` is `false` Defaults to `false`.
+| `objects` | `true` or `false` | Set empty objects for missing object values even if `defaults` is `false` Defaults to `false`.
+| `oneofs` | `true` or `false` | Set virtual oneof properties to the present field's name. Defaults to `false`.
+| `includeDirs` | An array of strings | A list of search paths for imported `.proto` files.
+
+The following options object closely approximates the existing behavior of `grpc.load`:
+
+```js
+const options = {
+  keepCase: true,
+  longs: String,
+  enums: String,
+  defaults: true,
+  oneofs: true
+}
+```
