-# Analog
+# @analogjs/trpc
 
-The fullstack meta-framework for Angular
+Angular/Nitro-based tRPC integration for Analog.
 
-Learn more at [analogjs.org](https://analogjs.org)
+## Features
+
+- Full tRPC v11 support
+- Angular integration with RxJS observables
+- Server-side rendering (SSR) support
+- Transfer state for hydration
+- Type-safe API calls
+
+## Installation
+
+```bash
+npm install @analogjs/trpc @trpc/client@^11.0.0 @trpc/server@^11.0.0
+```
+
+## Usage
+
+### Client Setup
+
+```typescript
+// trpc-client.ts
+import { AppRouter } from './server/trpc/routers';
+import { createTrpcClient } from '@analogjs/trpc';
+import { inject } from '@angular/core';
+import superjson from 'superjson';
+
+export const { provideTrpcClient, TrpcClient, TrpcHeaders } =
+  createTrpcClient<AppRouter>({
+    url: '/api/trpc',
+    options: {
+      transformer: superjson, // Optional: transformers are now handled via links
+    },
+  });
+
+export function injectTrpcClient() {
+  return inject(TrpcClient);
+}
+```
+
+### Server Setup
+
+```typescript
+// server/trpc/routers/index.ts
+import { router } from '../trpc';
+import { noteRouter } from './notes';
+
+export const appRouter = router({
+  note: noteRouter,
+});
+
+export type AppRouter = typeof appRouter;
+```
+
+### Component Usage
+
+```typescript
+// my-component.ts
+import { Component } from '@angular/core';
+import { injectTrpcClient } from './trpc-client';
+
+@Component({
+  selector: 'app-my-component',
+  template: `
+    @if (hello$ | async; as hello) {
+      {{ hello.greeting }}
+    }
+  `,
+})
+export class MyComponent {
+  private trpc = injectTrpcClient();
+  hello$ = this.trpc.hello.query({ name: 'Analog' });
+}
+```
+
+## tRPC v11 Migration
+
+This package now supports tRPC v11. The main changes include:
+
+- Transformers are now handled via links instead of the `transformer` option
+- Backward compatibility is maintained for existing transformer usage
+- Updated peer dependencies to require tRPC v11
+
+### Breaking Changes
+
+- `@trpc/client` and `@trpc/server` must be version 11.0.0 or higher
+- Transformers are now processed through links (backward compatible)
+
+## API Reference
+
+### `createTrpcClient<TRouter>(options)`
+
+Creates a tRPC client with Angular integration.
+
+#### Options
+
+- `url`: The base URL for tRPC API calls
+- `options.transformer`: (Deprecated) Use transformer link instead
+- `options.links`: Additional tRPC links
+- `batchLinkOptions`: Options for the HTTP batch link
+
+#### Returns
+
+- `TrpcClient`: Injection token for the tRPC client
+- `provideTrpcClient`: Provider function for Angular DI
+- `TrpcHeaders`: Signal for managing HTTP headers
