-# UNSTABLE Truncate
+# UNSTABLE Header
 
 > ⚠️ This component is UNSTABLE. It may significantly change at any point in the future.
 > Please use it with caution.
 
-Truncate is a component that truncates text based on defined number of rows.
+```jsx
+import { UNSTABLE_Header } from '@lmc-eu/spirit-web-react';
+
+<UNSTABLE_Header>{/* Content go here */}</UNSTABLE_Header>;
+```
+
+## Header
+
+Without any modifier, Header is ready to contain necessary blocks in a classic
+left-to-right layout (in LTR documents).
 
 ```jsx
-import { UNSTABLE_Truncate } from '@lmc-eu/spirit-web-react';
+<UNSTABLE_Header>
+  <Link href="/">
+    <ProductLogo>
+      <img src="https://www.example.com/logo.png" width="65" height="24" alt="Spirit" />
+    </ProductLogo>
+  </Link>
+</UNSTABLE_Header>
+```
+
+## Minimal Header
 
-<UNSTABLE_Truncate>{/* Text go here */}</UNSTABLE_Truncate>;
+The `isSimple` modifier can be used to create a minimal header.
+
+```jsx
+<UNSTABLE_Header isSimple>
+  <Link href="/">
+    <ProductLogo>
+      <img src="https://www.example.com/logo.png" width="65" height="24" alt="Spirit" />
+    </ProductLogo>
+  </Link>
+</UNSTABLE_Header>
 ```
 
-## Lines
+## Header Fluid
 
-You can add the number of lines to which you want to truncate the text using `lines` props
+The `isFluid` modifier can be used to create a fluid header.
 
 ```jsx
-<UNSTABLE_Truncate lines={2}>{/* Text go here */}</UNSTABLE_Truncate>
+<UNSTABLE_Header isFluid>
+  <Link href="/">
+    <ProductLogo>
+      <img src="https://www.example.com/logo.png" width="65" height="24" alt="Spirit" />
+    </ProductLogo>
+  </Link>
+</UNSTABLE_Header>
 ```
