+# Sample gRPC Node.js News Server
 
-```
+## Overview
+
+This repository contains a gRPC-based Node.js server implementing CRUD operations for a news list. It features a batched `GetNews` API, allowing efficient retrieval of multiple news items.
+
+### Features
+
+- **CRUD Operations**: Create, Read, Update, and Delete news items.
+- **Batched News Retrieval**: Fetch multiple news items in a single request.
+- **gRPC Interface**: Efficient and modern protocol for inter-service communication.
+
+## Prerequisites
+
+Before you begin, ensure you have installed:
+- [Node.js](https://nodejs.org/en/download/)
+- [npm](https://www.npmjs.com/get-npm)
+
+## Installation
+
+To set up the project, run the following command:
+
+```bash
 npm install
 ```
 
-```
+## Running the Server
+
+Start the server with:
+
+```bash
 node server
 ```
+
+## gRPC API
+
+The server uses the following gRPC API defined in `news.proto`:
+
+```protobuf
+syntax = "proto3";
+import "google/protobuf/empty.proto";
+
+message News {
+  int32 id = 1;
+  string title = 2;
+  string body = 3;
+  string postImage = 4;
+}
+
+service NewsService {
+  rpc GetAllNews (google.protobuf.Empty) returns (NewsList) {}
+  rpc GetNews (NewsId) returns (News) {}
+  rpc GetMultipleNews (MultipleNewsId) returns (NewsList) {}
+  rpc DeleteNews (NewsId) returns (google.protobuf.Empty) {}
+  rpc EditNews (News) returns (News) {}
+  rpc AddNews (News) returns (News) {}
+}
+
+message NewsId {
+  int32 id = 1;
+}
+
+message MultipleNewsId {
+  repeated NewsId ids = 1;
+}
+
+message NewsList {
+  repeated News news = 1;
+}
