# How to access custom array product files (manifests and product definition files) in MyIllumina

For custom and consortium arrays, the custom product files will be available for download from MyIllumina. These files include the .bpm and .csv versions of the Manifest and a Product Definition File (.xml) to be used with the Illumina Array Laboratory Information Management System (LIMS). Follow the instructions below for accessing custom or consortium array product files in MyIllumina.

1. Log in to MyIllumina from the [illumina.com](https://www.illumina.com/index-d.html) home page. To register for a MyIllumina account, select **New user? Sign up** on the login page.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://knowledge.illumina.com/microarray/iselect-custom-genotyping/microarray-iselect-custom-genotyping-reference_material-list/000001531.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.
