+
+Don't know what a handler is? See the [Architecture](../architecture#handler) section.
+
+:::
+
+## Requirements
+
+First, install the types for this adapter:
+
+```bash
+npm i --save firebase-functions firebase-admin
+```
+
+## Integrating with Http Events
+
+To use, you can import [HttpFirebaseHandler](../../api/Handlers/HttpFirebaseHandler) and call the method [setHandler](../../api/ServerlessAdapter#method-sethandler), as per the code below:
+
+```ts title="index.ts"
+import { ServerlessAdapter } from '@h4ad/serverless-adapter';
+import { DummyAdapter } from '@h4ad/serverless-adapter/lib/adapters/dummy';
+import { HttpFirebaseHandler } from '@h4ad/serverless-adapter/lib/handlers/firebase';
+import { DummyResolver } from '@h4ad/serverless-adapter/lib/resolvers/dummy';
+import app from './app';
+
+export const helloWorld = ServerlessAdapter.new(app)
+  .setHandler(new HttpFirebaseHandler())
+  .setResolver(new DummyResolver())
+  // choose the framework of your app
+  // .setFramework(new ExpressFramework())
+  .addAdapter(new DummyAdapter())
+  .build();
+
+// you can export more than one if you want
+export const test = ServerlessAdapter.new(app)
+  .setHandler(new HttpFirebaseHandler())
+  .setResolver(new DummyResolver())
+  // choose the framework of your app
+  // .setFramework(new ExpressFramework())
+  .addAdapter(new DummyAdapter())
+  .build();
+```
+
+:::info About Resolver and Adapter
+
+You should use DummyResolver and DummyAdapter because it's a requirement for the library, but HttpFirebaseHandler doesn't do anything with them,
+so you use those dummy versions just to satisfy the library requirements.
+
+:::
+
+## What about Cron, Pub/Sub, etc?
+
+I could not think yet in an API to handle those cases well,
+so currently I didn't add support to these type of Firebase Functions.
+
+If you have some idea about a design for those APIs, [create an issue](https://github.com/H4ad/serverless-adapter/issues/new/choose).
+
+## Examples
+
+You can see examples of how to use [here](https://github.com/H4ad/serverless-adapter-examples).
