+# How to Contribute
+
+We greatly appreciate contributions to the vscode-java-dependency project. Your efforts help us maintain and improve this extension. To ensure a smooth contribution process, please follow these guidelines.
+
+## Prerequisites
+- [JDK](https://www.oracle.com/java/technologies/downloads/?er=221886)
+- [Node.JS](https://nodejs.org/en/)
+- [VSCode](https://code.visualstudio.com/)
+
+## Build and Run
+
+To set up the vscode-java-dependency project, follow these steps:
+
+1. **Build the Server JAR**:
+   - The server JAR (Java application) is located in the [jdtls.ext](./jdtls.ext) directory.
+   - Run the following command to build the server:
+     ```shell
+     npm run build-server
+     ```
+
+2. **Install Dependencies**:
+   - Execute the following command to install the necessary dependencies:
+     ```shell
+     npm install
+     ```
+
+3. **Run/Debug the Extension**:
+   - Open the "Run and Debug" view in Visual Studio Code.
+   - Run the "Run Extension" task.
+
+4. **Attach to Plugin[Debug Java]**:
+   - Prerequisite: Ensure that the extension is activated, meaning the Java process is already launched. This is required for the task to run properly.
+   - Open the "Run and Debug" view in Visual Studio Code.
+   - Run the "Attach to Plugin" task.
+   - Note: This task is required only if you want to debug Java code [jdtls.ext](./jdtls.ext). It requires the [vscode-pde](https://marketplace.visualstudio.com/items?itemName=yaozheng.vscode-pde) extension to be installed.
+
+Thank you for your contributions and support!
