+### Usage
+
+1. Start by adding a Switch (eg. LabeledSwitch) in your xml layout as:
+
+    ```xml
+
+        <com.github.angads25.toggle.LabeledSwitch
+            android:id="@+id/switch1"
+            android:layout_width="wrap_content"
+            android:layout_height="wrap_content"
+            android:layout_margin="16dp"
+            android:textSize="14sp"
+            app:on="false"
+            app:colorBorder="@color/colorAccent"/>
+    ```
+
+2. To the reference of Switch in your Activity/Fragment class and set a ToggleListener to it as below:
+
+    ```java
+        LabeledSwitch labeledSwitch = findViewById(R.id.switch1);
+        labeledSwitch.setOnToggledListener(new OnToggledListener() {
+            @Override
+            public void onSwitched(LabeledSwitch labeledSwitch, boolean isOn) {
+                // Implement your switching logic here
+            }
+        });
+    ```
+    That's It. All your switching callbacks would be handled in onSwitched method, isOn will provide the current state of the switch.
+
