# Documents
In the master data of a product, we have implemented an additional configuration that allows you to display one or more documents as a download or embedded file.
## Create custom fields (optional)
We offer 3 pre-installed additional fields of the `media` type, allowing you to get started right away. Basically, you can create **as many files per product as you like**. To do this, you can simply create and assign more additional fields in the section. We have explained how to do this step by step here:
{% content-ref url="../../settings/custom-field-assignment/custom-fields-for-product-details" %}
[custom-fields-for-product-details](https://themedocs.zenit.design/en/settings/custom-field-assignment/custom-fields-for-product-details)
{% endcontent-ref %}
## Configuration
You can set the way documents are displayed in the theme configuration.
{% content-ref url="../../styling/product/documents" %}
[documents](https://themedocs.zenit.design/en/styling/product/documents)
{% endcontent-ref %}
## Set up
Using the **Custom fields (1)** in the product master data, you can upload up to three **Documents (1)** or use them from the media **(3)**.
{% hint style="info" %}
Useful file formats PDF, TXT, JPG, PNG or GIF. We recommend the use of PDF files.
{% endhint %}
Examples:
The visible **title (1)** in the download gallery as well as the **alt text (2)** can be managed in the media manager under "Content" > "Media".
