+# Discounts Twig functions
+
+Discounts Twig Functions allow you to operate on discounts in your templates.
+
+## Filters
+
+### `ibexa_render_discount_rule_type`
+
+This filter transforms the discount type (`fixed_amount` or `percentage`) into a human-friendly and translated label.
+
+``` html+twig
+{% set rule_type = discount.getRule().getType() %}
+
+<span class="ibexa-icon-tag">
+    <svg class="ibexa-icon ibexa-icon--small">
+        <use xlink:href="{{ ibexa_icon_path('discount-coupon') }}"></use>
+    </svg>
+    {{ rule_type|ibexa_render_discount_rule_type }}
+</span>
+```
+
+## Functions
+
+### `ibexa_discounts_render_discount_badge()`
+
+Use the `ibexa_discounts_render_discount_badge` to render a badge indicating the discounted amount, for example on product cards.
+
+``` html+twig
+{% if ibexa_storefront_are_discounts_enabled() %}
+    {% block product_discount_price_info %}
+        <div class="ibexa-store-product__discount-price-info">
+            {% include '@ibexadesign/storefront/component/discount/discount_price.html.twig' with {
+                original_price: original_price,
+            } %}
+            {% embed '@ibexadesign/storefront/component/discount/discount_badge.html.twig' with {
+                size: 'small',
+            } %}
+                {% block content %}
+                    {{- ibexa_discounts_render_discount_badge(discount, price_money) -}}
+                {% endblock %}
+            {% endembed %}
+        </div>
+    {% endblock %}
+{% endif %}
+```
+
+### `ibexa_get_original_price()`
+
+Displays the product price before the discount was applied.
+
+``` html+twig
+{{ ibexa_get_original_price(product)|ibexa_format_price ?: '-' }}
+```
+
+### `ibexa_format_discount_value()`
+
+Formats the discount value for each discount type, for example, by displaying `-10 EUR` or `-10%`.
+
+``` html+twig
+content: ibexa_format_discount_value(discount),
+```
+
+### `ibexa_discounts_is_active()`
+
+Helper function returning whether the discount is currently active.

+    <div>The discount is active</div>

+```
+
+### `ibexa_discounts_form_themes()`
+
+The `ibexa_discounts_form_themes` function serves as an extension point to provide new [form themes]([[= symfony_doc =]]/form/form_themes.html) for the discount form.
+
+To add new ones, create a class implementing the [FormThemeProviderInterface](/api/php_api/php_api_reference/classes/Ibexa-Contracts-Discounts-Admin-Form-FormThemeProviderInterface.html) interface and provide them in the `getFormThemes` method.
+
+### `ibexa_discounts_can_edit()`
