# Introduction This guide describes processes that applied when data downloads were possible by default. Data is now accessed through the UK Biobank Research Analysis Platform (please see [here](https://community.ukbiobank.ac.uk/hc/en-gb/community/posts/19996604847133-Changing-the-way-UK-Biobank-data-is-made-available-to-researchers-around-the-world)). This guide provides information for projects that have specifically been granted an exemption to download data and descriptive information about data that may have been downloaded prior to the change in policy. --- # Agent Instructions: 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: ``` GET https://uk-biobank.gitbook.io/data-access-guide/readme.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
