 ## Introduction
 
-In this tutorial, you'll learn how to generate code from your AsyncAPI document using the AsyncAPI generator tool.
+In this tutorial, you'll learn how to generate an application that uses [Glee](https://github.com/asyncapi/glee) framework. You'll do it with AsyncAPI document and [AsyncAPI CLI](/tools/cli).
 
 ## Background context
-The [AsyncAPI Generator](https://github.com/asyncapi/generator) is a tool that you can use to generate whatever you want based on the AsyncAPI document. You can generate docs and code. It can be used as a library in a Node.js application or through the [AsyncAPI CLI](https://github.com/asyncapi/cli).
+[Glee](https://github.com/asyncapi/glee) is a TS/JS framework that enables you to create APIs and messaging clients based on the AsyncAPI document. Instead of generating code, this framework tightly integrates with your AsyncAPI document and binds functions to specific AsyncAPI operations. You only have to provide the code for these functions and Glee will take care of the rest.
 
-The generator tool supports a number of templates to generate code for a variety of different languages and protocols as the output. These templates help to specify what exactly must be generated, and in this tutorial, you'll use a [Node.js template](https://github.com/asyncapi/nodejs-template).
+Glee is often used with the [AsyncAPI CLI](/tools/cli) for a better development experience.
+
+In the previous tutorial, you created an AsyncAPI document that is used in this tutorial.

+<Remember>
+
+If you did not follow the previous tutorial and do not have an `asyncapi.yaml` file for overview, then generate one by running the following command using AsyncAPI CLI:

     Let's break down the previous command:
-    - `asyncapi generate fromTemplate` is how you use AsyncAPI Generator via the AsyncAPI CLI. 
-    - ` asyncapi.yaml` is how you point to your AsyncAPI document and can be a URL. 
-    - `@asyncapi/nodejs-template` is how you specify the Node.js template.
-    - `-o` determines where to output the result.
-    - `-p` defines additional parameters you want to pass to the template. Here, the `server` parameter specifies the server's name as it is defined in AsyncAPI document.
+    - `asyncapi new glee` is how you use Glee via the AsyncAPI CLI. 
+    - `--name=tutorial` is how you tell the AsyncAPI CLI to name your new Glee project.

-
-## Introduction
-In this tutorial, you'll learn how to validate messages (events) that are sent to your AsyncAPI application.
-
-## Background context
-Message validation can be performed at both the **producer** and **consumer** levels. Message validation requires the participation of the producer, consumer, and broker. We will learn how to validate messages at the consumer level by discarding invalid messages based on the parameters provided.
-
-You will be using the [Eclipse Mosquitto](https://mosquitto.org/) broker. The MQTT protocol provides a lightweight method of messaging using a publish/subscribe model. You will also use an MQTT client that runs an MQTT library and connects to an MQTT broker over a network. Here publishers and subscribers are MQTT clients. The publisher and subscriber labels refer to whether the client is publishing or subscribing to receive messages.
-
-In the previous tutorial, you generated your application using the [AsyncAPI Generator](https://github.com/asyncapi/generator) Node.js template.
-<Remember>
-
-If you did not follow the previous tutorial and do not have an `asyncapi.yaml` file ready, then generate one by running: 
-`asyncapi new --example=tutorial.yml --no-tty`.
-
-Next, generate a server by running:
-
-    asyncapi generate fromTemplate asyncapi.yaml @asyncapi/nodejs-template -o output -p server=mosquitto
-    cd output && npm install
-
-</Remember>
-
-Now you will be validating the messages which you will be sending to your application using a Mosquitto broker and an MQTT client.
-
-## Validate messages
-In this step, you will send a message to your application using an MQTT broker and check the errors logged when you accidentally send an invalid message.
-
-1. Start your generated application.
-
-<CodeBlock language="bash">
-{`npm start`}
-</CodeBlock>
-
-2. Let's send a message:
-
-<CodeBlock language="bash">
-  {`mqtt pub -t 'light/measured' -h 'test.mosquitto.org' -m '{"id": 1, "lumens": "3", "sentAt": "2017-06-07T12:34:32.000Z"}'`}
-</CodeBlock>
-
-Go back to the previous terminal and check if your application logged the streetlight condition you just sent, with errors related to the invalid message. You should see something displayed in the terminal similar to the following:
-
-<CodeBlock language="bash">
-  {`light/measured was received:
-{ id: 1, lumens: '3', sentAt: '2017-06-07T12:34:32.000Z' }
-❗  Message Rejected. data.lumens should be integer`}
-</CodeBlock>
-
-Here, you can see that the property `lumens` has type `integer`, but you are sending a message with type `string`.
-
-<CodeBlock language="yaml" highlightedLines={[10,11]}>
-  {`  message:
-        name: lumensInfo
-        payload:
-          type: object
-          properties:
-            id:
-              type: integer
-              minimum: 0
-              description: Id of the streetlight.
-            lumens:
-              type: integer
-              minimum: 0
-              description: Light intensity measured in lumens.`}
-</CodeBlock>
-
-3. Send a correct message to your application:
-
-<CodeBlock language="bash">
-  {`mqtt pub -t 'light/measured' -h 'test.mosquitto.org' -m '{"id": 1, "lumens": 3, "sentAt": "2017-06-07T12:34:32.000Z"}'`}
-</CodeBlock>
-
-You can see that your generated application received a message in the terminal:
-
-<CodeBlock language="bash">
-  {`light/measured was received:
-{ id: 1, lumens: 3, sentAt: '2017-06-07T12:34:32.000Z' }`}
-</CodeBlock>
-
-This indicates that your message is valid and the application recieved it correctly.
-
-## Summary
-In this tutorial, you learned how to connect your generated application to an MQTT broker, send messages through it, identify when an invalid message is sent to your application, and how to correct an invalid message.
