# How to sign up for Bing Maps Developer Key?

A Bing Maps developer key is required to enable the mapping functionality of the SDK.

1. Sign-in to the [Bing Maps Dev Center.](https://www.bingmapsportal.com/Announcement?redirect=True\&WT.mc_id=github-mixedrealitycurriculum-ayyonet)
   * For new accounts, follow the instructions at [Creating a Bing Maps Account](https://docs.microsoft.com/bingmaps/getting-started/bing-maps-dev-center-help/creating-a-bing-maps-account?WT.mc_id=github-mixedrealitycurriculum-ayyonet).
2. Select **My keys** under **My Account**, and select the option to create a new key.
3. Provide the following required information to create a key:
   * **Application name**: The name of the application.
   * **Key type**: *Basic* or *Enterprise*. Key types are explained [here](https://www.microsoft.com/maps/create-a-bing-maps-key?WT.mc_id=github-mixedrealitycurriculum-ayyonet).
   * **Application type**: Select *Other Public Mobile App*.
4. Click the **Create** button. The new key displays in the list of available keys. This key will be used later when setting up the Unity project.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.xrdev.app/mixed-reality-docs/lessons/lesson-5/project/how-to-sign-up-for-bing-maps-developer-key.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
