## 🔐 Certificate Installation (for HTTPS Traffic Capture)

* When capturing HTTPS traffic (from browsers or mobile devices), Loadmill installs a local root certificate to decrypt HTTPS traffic
* During installation, accept the certificate prompt to allow HTTPS capture
* If using for mobile capture: export and install the certificate on the mobile device via Wi-Fi proxy configuration
* Ensure both desktop and mobile device are on the same Wi-Fi network for proper capture

## 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://docs.loadmill.com/introduction/deviceless-mobile-testing/installing-loadmill-desktop-app/install-windows-desktop-app.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.
