# How to determine the appropriate kit configuration to use based on the data needed?

To determine the number of reads needed for the run (project), multiply the desired reads per sample by the number of samples in the pool. With the total number of reads, identify the kit and sequencer that fits the data needs using the sequencer specifications pages, listed below.

# 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://knowledge.illumina.com/instrumentation/general/instrumentation-general-faq-list/000006622.md?ask=<question>
```

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.
