 Just instantiate and bind it to your state. That is it!
 ```swift
 @State private var selectedTabIndex = 0
-SlidingTabView(selection: $selectedTabIndex,tabs: ["First Tab", "Second Tab"]
+SlidingTabView(selection: $selectedTabIndex,tabs: ["First Tab", "Second Tab"])
 ```
 
+If need disabled button tabs:
+```swift
+@State private var selectedTabIndex = 0
+SlidingTabView(selection: $selectedTabIndex,tabs: ["First Tab", "Second Tab"], isEnabled: false)
+```
+
+If need change manually a tab:
+```swift
+@State private var selectedTabIndex = 0
+SlidingTabView(
+    selectionState:self.$selectedTabIndex,
+    selection: $selectedTabIndex,
+    tabs: ["First Tab", "Second Tab"], isEnabled: false
+)
+```
+
+To change the tab, change the value of selectionState and selection
