+### Usage
 
 ### Generate OTP
+```java
+import com.oluwatunmise.FastOTP;
+import com.oluwatunmise.external.*;
+
+public class Main {
+  public static void main(String[] args) throws Exception {
+    String apiKey = "xxx_xxx";
+    FastOTP fastOTP = new FastOTP(apiKey);
+
+    OTPDelivery otpDelivery = new OTPDelivery("[email protected]");
+    GenerateOTP generateOTP = new GenerateOTP(
+        10, 
+        6, 
+        "alpha_numeric",
+        "java_test", 
+        otpDelivery
+    );
+    BaseResponse baseResponse = fastOTP.GenerateOTP(generateOTP);
+
+    if (baseResponse.getSuccess()) {
+      BaseSuccessResponse baseSuccessResponse = (BaseSuccessResponse) baseResponse.getData();
+      System.out.println(baseSuccessResponse.getOtp().getDeliveryDetails());
+      System.out.println(baseSuccessResponse.getOtp().getIdentifier());
+    }else {
+      BaseErrorResponse baseErrorResponse = (BaseErrorResponse) baseResponse.getData();
+      System.out.println(baseErrorResponse.getErrors());
+      System.out.println(baseErrorResponse.getMessage());
+    }
+  }
+}
+```
 ### Validate OTP
+```java
+import com.oluwatunmise.FastOTP;
+import com.oluwatunmise.external.BaseErrorResponse;
+import com.oluwatunmise.external.BaseResponse;
+import com.oluwatunmise.external.BaseSuccessResponse;
+import com.oluwatunmise.external.ValidateOTP;
+
+public class Main {
+  public static void main(String[] args) throws Exception {
+    String apiKey = "xxx_xxx";
+    FastOTP fastOTP = new FastOTP(apiKey);
+
+    ValidateOTP validateOTP = new ValidateOTP("your_identifier", "4567");
+    BaseResponse baseResponse = fastOTP.ValidateOTP(validateOTP);

+    if (baseResponse.getSuccess()) {
+      BaseSuccessResponse baseSuccessResponse = (BaseSuccessResponse) baseResponse.getData();
+      System.out.println(baseSuccessResponse.getOtp().getDeliveryDetails());
