+# UNSTABLE Header
+
+⚠️ This component is UNSTABLE. It may significantly change at any point in the future.
+Please use it with caution.
+
+The `UNSTABLE_Header` component is planned to replace the `Header` component in the future.
+
+This component provides these components:
+
+- [UNSTABLE_Header](#unstable-header)
+- [UNSTABLE_HeaderLogo](#unstable-headerlogo)
+
+## UNSTABLE Header
+
+The `UNSTABLE_Header` component is a main wrapper which provides mainly the visual for the Header.
+
+```html
+
+```
+
+It also sets CSS variable for the Header height which can be used in other nested components.
+
+## UNSTABLE HeaderLogo
+
+The `UNSTABLE_HeaderLogo` component is a container for the logo.
+
+```html
+
+```
+
+It inherits the `UNSTABLE_Header` height and sets the logo wrapper height to the same value.
+
+You can use the `ProductLogo` component inside the `UNSTABLE_HeaderLogo` component.
+
+```html
+
+```
+
+## Component Composition
+
+Use [`Container`][web-container] and [`Flex`][web-flex] components to create a layout for the Header content.
+
+```html
+
+```
+
+This way you can modify the layout of the Header content easily and modify it how you need.
+
+For example you can make the content centered by setting the `Flex` alignment classes to center.
+
+```html
+
+```
+
+Or you can make modify gaps between the content by setting the `Flex` spacing styles.
+
+```html
+
+```
+
+If you need the whole Header fluid you can do it by adding the `Container--fluid` class to the `Container`.
+
+```html
+
+```
