# Search docs and the provider registry in VS Code

> Use the Docs view in Astro for VS Code to search Airflow, Astronomer, and provider documentation, add a provider to requirements.txt, and insert an operator at your cursor.

<Info>
  **Labs**

  This feature is in [Labs](/docs/astro/feature-previews).
</Info>

The **Docs** view in Astro for VS Code searches Airflow documentation, Astronomer documentation, and the Airflow provider registry from your editor's sidebar. Each result opens as a rendered page in an editor tab. A provider registry result, such as an operator, hook, or sensor, also lets you add the provider to your project and insert a call to it in your Dag.

You don't need to sign in to Astro to search.

## Search the docs

1. Open the **Docs** view in the Astro sidebar.
2. Enter a question in **Search the Astronomer docs** and press **Enter**.

The view lists the closest matches, with a summary of each. Every search returns results, so use the summaries to decide whether a match answers your question.

To choose the Airflow version that results match, use the dropdown menu next to the search box. The default is **Airflow 3**.

Click a result to open it in an editor tab.

## Add a provider to requirements.txt

On a provider registry result, click **Add to requirements.txt**.

The extension adds the provider package to the `requirements.txt` file of the Astro project open in your window, pinned to the version that the registry entry describes, and shows you the line it added. To undo the change, press **Cmd+Z** or **Ctrl+Z** in the file.

* If `requirements.txt` already lists the package, the extension shows you that line and doesn't change it, even if the version is different.
* If the registry doesn't name a released version for the provider, the extension adds the package without a version.

To install the package, restart your local Airflow environment. See [Add providers and packages](/docs/cli/v1.46/add-providers-packages).

## Insert an operator or hook at your cursor

1. Open the Python Dag file and place your cursor where you want the call.
2. On a provider registry result, click **Insert snippet**.

The extension adds the import statement with your file's other imports, and inserts a call at your cursor with a placeholder for each required parameter. Press **Tab** to move between placeholders.

## Ask Otto about a registry entry

On a provider registry result, click **Ask Otto** to start a chat about it. For example, ask Otto how to use an operator in your Dag. See [Chat with Otto in VS Code](/docs/astro/vscode/vscode-otto-chat).
