-This module is part of `JDevKit`, an open-source Java Development Kit that provides a set of
-convenient tools to streamline code development and enhance productivity. This module serves as the
-useful toolkit for the library, contains a collection of utility classes commonly used in all Java
-Application development.
+This module provides a set of utilities to streamline Java codes.
 
-## Prerequisites
+## Features
 
-This whole `JDevKit` is developed by **JDK 17**, which means you have to use JDK 17 for
-better experience.
+- AES encryption and decryption;
+- Base64 encode and decode;
+- Boolean calculation;
+- Reduce `if...else...` with **lambdas**;
+- Hash calculation for strings;

+- Simplified range generator.
 
-## Installation
-
-### If you are using `Maven`
-
-It is quite simple to install this module by `Maven`. The only thing you need to do is find your
-`pom.xml` file in the project, then find the `<dependencies>` node in the `<project>` node, and add
-the following codes to `<dependencies>` node:
-
-```xml
-<dependency>
-	<groupId>com.onixbyte</groupId>
-    <artifactId>devkit-utils</artifactId>
-    <version>${devkit-utils.version}</version>
-</dependency>
-```
-
-And run `mvn dependency:get` in your project root folder(i.e., if your `pom.xml` is located at
-`/path/to/your/project/pom.xml`, then your current work folder should be `/path/to/your/project`),
-then `Maven` will automatically download the `jar` archive from `Maven Central Repository`. This
-could be **MUCH EASIER** if you are using IDE(i.e., IntelliJ IDEA), the only thing you need to do
-is click the refresh button of `Maven`.
-
-If you are restricted using the Internet, and have to make `Maven` offline, you could follow the
-following steps.
-
-1. Download the `jar` file from any place you can get and transfer the `jar` files to your 
-   work computer.
-2. Move the `jar` files to your local `Maven` Repository as the path of 
-   `/path/to/maven_local_repo/com/onixbyte/devkit-utils/`.
-
-### If you are using `Gradle`
-
-Add this module to your project with `Gradle` is much easier than doing so with `Maven`.
-
-Find `build.gradle` in the needed project, and add the following code to the `dependencies` closure
-in the build script:
-
-```groovy
-implementation 'com.onixbyte:devkit-utils:${devkit-utils.version}'
-```
