+<!-- Usage -->
+## Usage
+
+### 1. Create TabifyItems Enum
+
+> Make sure your enum implements the `TabifyItem` protocol.
+
+```swift
+enum TabifyItems: Int, TabifyItem {
+    case home = 0
+    case search
+    case profile
+
+    var icon: String {
+        switch self {
+            case .home: return "house"
+            case .search: return "magnifyingglass"
+            case .profile: return "person"
+        }
+    }
+
+    var title: String {
+        switch self {
+            case .home: return "Home"
+            case .search: return "Search"
+            case .profile: return "Profile"
+        }
+    }
+}
+```
+
+### 2. Add Tabify View
+
+```swift
+Tabify(selectedItem: $tabBarSelection) {
+    Text("Home")
+    .tabItem(for: TabifyItems.first)
+
+    Text("Search")
+    .tabItem(for: TabifyItems.second)
+
+    Text("Profile")
+    .tabItem(for: TabifyItems.third)
+}
+/* This following modifiers are optional. You can use them to inject your custom bar and item styling. */
+.barStyle(style: CustomTabifyBarStyle())
+.itemStyle(style: CustomTabifyItemStyle())
+```
