+A simple electron main process framework.
+<p>
 
 ## Description
 
 Einf is a simple electron main process framework, which provides some decorators and automatic dependency injection to help you simplify the main process code.
 
+## Features
+
+- 💉‍ Support dependency injection powered by Typescript decorators.
+
+- 🪟 Support custom items injection and window object injection.
+
+- 🔗 Automatic ipc event binding to reduce duplication of code.
+
+- 📦 Tiny size, the whole framework is less than 10kb.
+
+- 💡 Simple to use, you can use it as a base framework to build your own framework.
+
+## Installation
+
+```shell
+npm i einf
+# Or Yarn
+yarn add einf
+# Or PNPM
+pnpm add einf
+```
+
+## Usage
+
+Entry point of your electron application like `index.ts`: 
+
+```ts
+import { BrowserWindow, app } from 'electron'
+import { createEinf } from 'einf'
+import { AppController } from './app.controller'
+
+async function bootstrap() {
+  const window = new BrowserWindow()
+  window.loadURL('https://github.com')
+
+  await createEinf({
+    // window to create
+    window,
+    // controllers will be automatically initialized
+    controllers: [AppController],
+    // custom items to inject
+    injects: [{
+      name: 'IS_DEV',
+      inject: !app.isPackaged,
+    }],
+  })
+}
+
+bootstrap()
+```
+
+Provide at least one controller to start the application, `app.controller.ts`:
+
+```ts
+import type { BrowserWindow } from 'electron'
+import { app } from 'electron'
+import { Controller, Inject, IpcInvoke, IpcOn, Window } from 'einf'
+import type { AppService } from './app.service'
+
+@Controller()
+export class AppController {
+  constructor(
+    private appService: AppService,
+    @Inject('IS_DEV') private isDev: boolean,
+    @Window() private win: BrowserWindow,
+  ) {}
+
+  @IpcOn('reply-msg')
+  public replyMsg(msg: string) {
+    return msg
+  }
+
+  @IpcInvoke('send-msg')
+  public sendMsg(msg: string) {
+    console.log(msg)
+    return 'Get msg'
+  }
+
+  @IpcInvoke('exit')
+  public exit() {
+    app.quit()
+  }
+}
+
+```
+
+You can also inject service via `@Injectable` decorator, `app.service.ts`:
+
+```ts
+import { Injectable } from 'einf'
+
+@Injectable()
+export class AppService {
+  public createMsg(msg: string): string {
+    return `"${msg}" is created by app service`
+  }
+}
+
+```
