+Unofficial Java package for Chapa Payment Gateway.
 
-Unofficial Java SDK for Chapa Payment Gateway.
-
-## What's new in this version
-- You no longer need to deal with `JSON` or `Map<String, Object>` responses. You can just treat response data as a Java object using specific response classes for each request type (e.g. payment initialization, payment verification).
-- Better exception handling. The SDK will throw the newly added `ChapaException` on failed requests to Chapa API.
-- Bug fixes and design improvements.
-- Well-tested and documented code. Check out the Javadoc [here](https://yaphet17.github.io/chapa-java/). 
+## Features
+- You can now implement `IChapaClient` interface and create your own custom implementation
+  to use your favorite HTTP client.
+- Includes split payment feature added by Chapa. You can now get list of supported banks, create
+  sub-account and perform a split payment. See [Split Payment](https://developer.chapa.co/docs/split-payment/) documentation for more details.
+- Additional utility methods to help you to generate a convenient token for your transactions, to map json string
+  to `PostData` object etc.

 ## Installation
  Add the below maven dependency to your `pom.xml` file.
 ```xml
     <dependency>
-      <groupId>io.github.yaphet17</groupId>
-      <artifactId>Chapa</artifactId>
-      <version>1.2.2</version>
+      <groupId>com.github.amenski</groupId>
+      <artifactId>chapa</artifactId>
+      <version>1.0.0</version>
     </dependency>
 ```
 Or add the below gradle dependency to your `build.gradle` file.
 ```groovy
-    implementation 'io.github.yaphet17:Chapa:1.2.2'
+    implementation 'com.github.amenski:chapa:1.0.0'
 ```
 
 ## Usage
 
+> **Note** : This doc might not fully cover chapa-api. Please refer to the chapa developer doc for more. And contributions are welcome too. Thanks.
+
+
 Instantiate a `Chapa` class.
 ```java       
-Chapa chapa = new Chapa("your-secrete-key");
+Chapa chapa = new Chapa.ChapaBuilder()
+        .client(new ChapaClient()) // --> default implementation
+        .secretKey("secret-key")
+        .build();
 ```
-Or if you want to use your own implementation of `ChapaClient` interface.
+Or if you want to use your own implementation, implement the methods from `IChapaClient` interface.
 ```java
-Chapa chapa = new Chapa("your-secrete-key", new MyCustomChapaClient());
-```
-Note: `MyCustomChapaClient` must implement `ChapaClient` interface.
+import com.github.amenski.client.ChapaClient;
+
+public class MyCustomChapaClient implements IChapaClient {
+  ...
+}
+
 
-To initialize a transaction, you can specify your information by either using our `PostData` class.
+Chapa chapa = new Chapa(new MyCustomChapaClient(), "secrete-key");
+```
 
-Note: Starting from version 1.1.0 you have to specify customization fields as a `Map<String, String>` object.
+## Retries (with ExponentialBackoff)
+To add retries to clients, use `RetrierRetrofitClientProvider`. This class allows configuring 3 retries if a call fails.
+Provides retrofit client to make calls to chapa api. <br>
+Retry will be done with an <a href="https://en.wikipedia.org/wiki/Exponential_backoff">ExponentialBackoff</a> strategy.<br>
+<pre>
+Example usage:
+public class CustomChapaClient implements IChapaClient {
+    private String baseUrl = "https://api.chapa.co/v1/";
+    private ChapaClientApi chapaClientApi;
+    .
+    .
+    private void buildApiClient() {
+         if (isBlank(baseUrl)) throw new ChapaException("Unable to create a client. Api baseUrl can't be empty");
+         chapaClientApi = new RetrierRetrofitClientProvider().buildClient(ChapaClientApi.class, baseUrl);
+    }
+}
+</pre>

+
+To initialize a transaction, you simply need to specify your information by either using our `PostData` class.
