+# JDevKit
+JDevKit is a Java Development Kit that offers a set of convenient tools for writing code efficiently.
+
+## Modules
+### `guid`
+A module for generating globally unique IDs. It includes a facade interface and an implementation of GUID generation using the Snowflake algorithm. More globally unique ID generation modes will be added in the future.
+
+### `dev-utils`
+A collection of common utility classes to simplify Java development. It includes tools for Base64 encoding/decoding of strings, reducing if-else code blocks using Lambda expressions, converting between maps and arbitrary objects, high-precision chained mathematical calculations, and string hashing or message digest calculations.
+
+### `simple-jwt-facade`
+A facade for Simple JWT (JSON Web Token) implementations in Java. This module provides a unified interface to work with JWTs regardless of the underlying implementation.
+
+### `simple-jwt-auth0`
+A Simple JWT implementation using the com.auth0:java-jwt library.
+
+### `simple-jwt-jjwt`
+A Simple JWT implementation using the io.jsonwebtoken:jjwt library.
+
+### `simple-jwt-spring-boot-starter`
+A Spring Boot auto-configuration wrapper for the simple-jwt module, making it easier to integrate JWT functionality into Spring Boot applications.
+
+### `sms-sender-facade`
+A facade for sending SMS messages in Java. This module abstracts the interfaces of various SMS service providers.
+
+### `sms-sender-aliyun`
+An implementation of SMS Sender using the Alibaba Cloud (Aliyun) service.
+
+### `sms-sender-tencent`
+An implementation of SMS Sender using the Tencent Cloud service.
+
+### `sms-sender-spring-boot-starter`
+A Spring Boot auto-configuration wrapper for the sms-sender module, simplifying the integration of SMS sending capabilities into Spring Boot applications.
