+# `@depot/connectrpc-workers`
+
+A [Connect RPC](https://connectrpc.com/) adapter for [Cloudflare Workers](https://workers.cloudflare.com/).
+
+## Installation
+
+You can install the module with your favorite package manager:
+
+```bash
+pnpm add @depot/connectrpc-workers
+```
+
+This package depends on the peer dependencies `@connectrpc/connect` and `@cloudflare/workers-types`.
+
+## Usage
+
+You can construct a function to register handlers for your Connect services, then construct a Cloudflare Workers fetch event handler from those routes:
+
+```typescript
+import type {ConnectRouter} from '@connectrpc/connect'
+import {connectWorkersAdapter} from '@depot/connectrpc-workers'
+
+function routes(router: ConnectRouter) {
+  // implement rpc Say(SayRequest) returns (SayResponse)
+  router.rpc(ElizaService, ElizaService.methods.say, async (req) => ({
+    sentence: `you said: ${req.sentence}`,
+  }))
+}
+
+const handler = connectWorkersAdapter({routes})
+
+export default {
+  fetch(request, env, context) {
+    return handler(request, env, context)
+  },
+} satisfies ExportedHandler
+```
