# Document your APIs from the Postman VS Code extension

When you create a collection, Postman automatically generates basic documentation that includes details about requests and sample code in various client languages. Using the built-in editor, you can add a description, include links, and add images and videos. By including documentation in your collections, it provides more context and detail, making it more useful to users.

## Write documentation

Teammates with the Editor role can add descriptions to collections, folders, and requests. You can write your descriptions using the [visual editor](/docs/publishing-your-api/authoring-your-documentation/#write-descriptions-in-the-postman-editor) or you can enter Markdown syntax.

To add a description to a collection or folder, do the following:

1. Click <img alt="Collection icon" src="https://assets.postman.com/postman-docs/aether-icons/entity-collection-stroke.svg#icon" width="16px" /> **Collections**, then select a collection or folder.
2. Enter a description in the **Overview** tab.
3. Click outside the editor to save your description.

To add a description to a request, do the following:

1. Click <img alt="Collection icon" src="https://assets.postman.com/postman-docs/aether-icons/entity-collection-stroke.svg#icon" width="16px" /> **Collections**, then select a request.
2. Click **View Documentation** in the upper right.
3. Enter a description.
4. Click outside the editor to save your description.

To learn more about writing documentation, see [Write documentation in Postman](/docs/publishing-your-api/authoring-your-documentation/).

## View documentation

You can view a collection's complete documentation that includes each request's description. Documentation also includes details such as the request's method and URL, authorization, and any headers or parameters. For each request, you can view sample code in various client languages, and example response bodies and headers.

To view the complete documentation for a collection, do the following:

1. Click <img alt="Collection icon" src="https://assets.postman.com/postman-docs/aether-icons/entity-collection-stroke.svg#icon" width="16px" /> **Collections**, then select a collection.
2. In the **Overview** tab, click **View complete documentation**. The Postman VS Code extension opens the complete documentation in a new tab.

You can also customize the language used in the collection's sample code. In the complete documentation view, click the **Language** tab, then select a language from the list. The documentation updates each request with the selected language.
