# Creating your first workflow

The goal of this example is to create a flow with a PDF file and a question as inputs, and to generate the answer to the question as the output. In our case, we are going to use a document that discusses COVID-19 and ask the AI to answer questions related to the document.

Use this guide to create a simple Workflow that summarizes a YouTube video.

In this example, the user pastes a YouTube link, and Diaflow returns a summary.

## Create the Workflow

1. Click **New.**
2. Choose **New flow.**
3. Choose **Continue**.
4. Select how the Workflow should start.

Choose the start type that matches your use case:

* The **3 options on top** (On app event, Schedule, Webhook) create an **Automation** Workflow.
* The **2 options on the bottom left** (Click a button, Submit a form) create an **App** Workflow.
* Select **Chat** to create a **Chatbot** Workflow (**Simple** or **Expert**).

For this example, choose **Submit a form**.

## Build the Workflow

1. In **Trigger**, click **Add**.
2. Choose `Short Text`.
3. Name the field `YouTube URL`.

4. Click or drag from the green dot on the right side of **Trigger**.
5. Search for **YouTube**.
6. Select it as the next step.
7. In the URL field, type **@** to show the node list and select `trigger.youtube_url`.
8. Set **Detect Language** to `Auto Generate`.

The Pop-up will display the search keyword "YouTube."

9. Add an AI node such as **OpenAI**.
10. Choose the connection and model you want to use.
11. In the prompt, ask the AI to summarize the video.
12. Insert the result from the **YouTube** node.

Use a simple prompt like this:

```
Summarize this YouTube video in 3 to 5 bullet points.
Include the main idea and key takeaways.
```

13. Finally, add an **Output** node at the **end** of the flow.
14. In **Output**, click **Add**.
15. Select the result from the AI node.
16. If needed, also add the result from the **YouTube** node.
