Datasheets can be added via custom fields and are displayed in the datasheets tab on the product page - **without any template adjustment.**
{% endhint %}
{% stepper %}
{% step %}
### Create custom field
You can create any custom field via *Settings > System > Custom fields*.
**Select or create set:** To do this, either select the existing `Datasheets (THEME NAME)` set or create your own set. When creating a new set, make sure to assign to products.
**Create custom field:** In the desired set, create a new field of **type (1)** `Media field` using **New custom field**. You can find further information on [creating custom fields](https://docs.shopware.com/en/shopware-6-en/settings/custom-fields#media) in the Shopware documentation.
In our example we call the custom field `custom_details_example`.
{% endstep %}
{% step %}
### Assign custom field
You can access the theme settings via *Extensions > My Extensions > Tab: Themes > \[Select theme] > Configure*. In the **Custom fields for product datasheets (1)** selection you can now **search (2)** for the newly created custom field and **select (3)** it.
{% endstep %}
{% step %}
### Create content
In order for the custom field to be visible in the storefront, you must enter content for the respective product. Under *Catalogues > Products > \[Select product] > in the tab: Specifications* you will find the custom fields at the very bottom. Select the set in which the custom field was created and set a media to it (1).
{% endstep %}
