+# HTTP Client Configuration for Local Testing  
+
+This file is designed for local testing of HTTP interfaces using the **HTTP Client** plugin in IntelliJ IDEA. It enables quick testing of REST APIs directly within the IDE without requiring additional external tools or scripts.  
+
+## Prerequisites  
+1. Install IntelliJ IDEA (Community or Ultimate Edition).  
+2. Install the **HTTP Client** plugin if it is not already installed.  
+
+   For more information on the HTTP Client plugin, refer to the official documentation:  
+   [HTTP Client in IntelliJ IDEA](https://www.jetbrains.com/help/idea/http-client-in-product-code-editor.html)  
+
+## How to Use  
+1. Open the `.http` or `.rest` file in IntelliJ IDEA.  
+2. Use the provided HTTP requests to test your API endpoints.  
+3. Select an HTTP request and click the **Run** button that appears next to it in the editor, or press `Ctrl+Enter` (Windows/Linux) or `Command+Enter` (Mac).  
+4. View the response in the dedicated response panel.  
+
+### Example  
+```http
+GET http://localhost:8080/api/example
+Content-Type: application/json
+Authorization: Bearer <your_token>
+```
+
+### Features
+
+-   Supports HTTP methods like GET, POST, PUT, DELETE, etc.
+-   Easily add headers, query parameters, and body content.
+-   View responses interactively with support for formats like JSON, XML, etc.
+
+## Scope of Use
+
+This file is intended **only for local development and testing purposes**. It is not meant for production or CI/CD pipelines.
+
+## Recommendations for Automated Testing
+
+While the HTTP Client plugin is great for manual testing, we recommend integrating REST API tests into your automated test suite for better coverage and reliability.
+
+### Other Suggested Tools
+
+-   **JUnit** with [RestAssured](https://rest-assured.io/) for Java-based integration tests.
+-   **Postman** with [Newman](https://www.npmjs.com/package/newman) for automated API testing.
