 ## Description
 
-Java package relevant tools, source code、macros and guidance docs.
+This repository serves as the entry point repository for the Java SIG and is used as a repository for the openEuler community's Java packaging-related code, macros, tools, and guidelines. In addition, we identify packages to be maintained in the following categories.
+
+1. Java build tool ontology packages, such as `maven` `gradle` `ant` and so on. 
+2. Java build tool-related derivative packages, such as `maven_local` and so on. 
+3. Java packages on which above Java build tool depends. 
+4. Java packages, and the Java packages on which they depend.
+5. Java packages, and the specialized packages on which they depend (specifically to support the Java software).

 ## 介绍
 
-该仓库用于存放 openEuler 社区 Java 打包相关代码、宏、工具，以及指引文档。
+该仓库作为 Java SIG 的入口仓库，用于存放 openEuler 社区 Java 打包相关代码、宏、工具，以及指引文档。此外，我们明确需要维护的软件包分为如下几类：
+
+1. Java 构建工具本体软件包，例如 `maven` `gradle` `ant` 等。
+2. Java 构建工具相关衍生软件包，例如 `maven_local` 等。
+3. Java 构建工具所依赖的 Java 软件包。
+4. Java 软件包，及其所依赖的 Java 软件包。
+5. Java 软件包，及其所依赖的专用软件包（专门用于支撑该 Java 软件）。
