# Train Your Hotel Chatbot with Files

> Upload hotel documents and apply updates

Use **Knowledge Base → File** to add reference documents such as guest information, hotel policies, menus, and facility details.

## Supported formats

The upload screen lists **PDF, DOCX, TXT, CSV, and Excel** files, with a **10 MB maximum**.

## Upload a document

1. Open **Knowledge Base** and select **File**.
2. Click **Select Files**, or drag files into the upload area.
3. Check that the selected files are current and suitable for guest-facing answers.
4. Click **Upload Files**.
5. Review the **Training Sources** list.
6. Click **Retrain Chatbot** and wait for the success confirmation.
7. Use **Test your chatbot** to check questions based on the uploaded document.

## Keeping documents current

Replace or update source documents when policies, opening hours, menus, or offers change. Remove obsolete training sources using the delete control where appropriate. **Retrain again after every relevant change.**

## Good practices

* Use clearly named, current documents.
* Avoid uploading internal-only, confidential, or guest-personal information.
* Remove superseded menus and expired promotional information.
* Test important answers after retraining.

## FAQ

### I uploaded a new PDF. Why does the bot still give the previous information?

Uploading and retraining are separate steps. Click **Retrain Chatbot** after the upload and test again.

### Can I upload a document larger than 10 MB?

The current upload screen specifies a maximum of 10 MB per file. Reduce or split larger documents before uploading.
