# Uploading documents

> File types, size limits, processing statuses, and how to fix a failure.

## Upload

<Steps>
  <Step title="Open Knowledge">
    **Resource settings → Knowledge**.
  </Step>

  <Step title="Click Upload">
    In the Documents section header. You can select several files at once.
  </Step>

  <Step title="Wait for indexing">
    The status column updates live and the table refreshes itself while processing.
  </Step>
</Steps>

Once a document reads **Indexed**, the agent can use it.

## What you can upload

| Format         | Extension |
| -------------- | --------- |
| PDF            | `.pdf`    |
| Microsoft Word | `.docx`   |
| Markdown       | `.md`     |

Maximum **100 MB** per file, and PDFs up to **500 pages**.

## Statuses

| Status      | Meaning                            |
| ----------- | ---------------------------------- |
| Pending     | Queued                             |
| Parsing     | Pulling content out of the file    |
| Extracting  | Identifying key information        |
| Chunking    | Splitting into searchable sections |
| Indexing    | Storing sections for search        |
| **Indexed** | Ready to use                       |
| Failed      | Something went wrong               |

## Categories are automatic

Every document is classified for you. You do not pick, and you cannot override it, which keeps classification consistent.

| Category              | Covers                                            |
| --------------------- | ------------------------------------------------- |
| About & Locations     | Dealership info, contact details, hours           |
| Brand & OEM           | Brand history, manufacturer information           |
| Financing & Insurance | Financing options, loan terms, insurance products |
| Service & Parts       | Service procedures, parts, maintenance, warranty  |
| Policies              | Returns, terms, privacy, cancellation             |
| Promotions & Events   | Promotions, events, discounts, seasonal deals     |
| Products & Specs      | Specs, features, technical details, manuals       |

## Managing documents

* **Delete** — the **more actions** menu (three dots) on the row. Removed immediately, and the agent stops using it.
* **Re-index** — same menu, but only appears on **Failed** documents.

## When a document fails

Usually one of three causes:

1. **A scanned PDF with no text layer.** The most common one. Images of text cannot be parsed. Re-save with OCR, or retype the content.
2. **Password-protected.** Remove the protection and re-upload.
3. **Corrupted.** Confirm it opens on your own machine.

Try **Re-index** first. If it fails again, look at the three causes above rather than re-uploading the same file repeatedly.

## How many is too many

There is no fixed document limit. But each reply draws on a limited amount of context, so the agent selects only the most relevant sections per question.

<Tip>
  A few well-organised documents beat many overlapping ones. Two documents that disagree about your return policy give the agent no way to pick the right answer.
