+
+## Basic usage
+
+Render a tab with label:
+
+```html
+<adf-info-drawer>
+
+    <adf-info-drawer-tab [label]="'Tab1'">
+        <div> Tab1 content</div>
+    </adf-info-drawer-tab>
+
+    <adf-info-drawer-tab [label]="'Tab2'">
+        <div> Tab2 content</div>
+    </adf-info-drawer-tab>
+</adf-info-drawer>
+```
+
+Render tab with icon instead of labels:
+
+```html
+<adf-info-drawer>
+
+    <adf-info-drawer-tab [label]="'Tab1'" icon="comment">
+        <div> Tab1 content</div>
+    </adf-info-drawer-tab>
+
+    <adf-info-drawer-tab [label]="'Tab2'" icon="people">
+            <div> Tab2 content</div>
+    </adf-info-drawer-tab>
+
+</adf-info-drawer>
+```
