-Artifactory Sample User Plugins
-===============================
+# Artifactory User Plugins
 
-### Note : Many of the artifactory user plugins are no longer compatible with the recent versions of Artifactory particularly after JDK17 support introduced in 7.43 and above.These deprecated plugins have been moved to the [deprecated directory] .**
+> **Note**: JFrog Workers is the recommended cloud-native solution for extending the JFrog Platform (including Artifactory). While user plugins are still supported, we recommend using JFrog Workers where possible for better scalability, security, and performance. [Learn more about JFrog Workers](https://jfrog.com/help/r/ybbUNZGwwAmzW2qGyL9Zdw/I4E5sOhWWpIHHfdV37__Iw).

+## Upgrade Notice
 
+1. **Groovy 4 Upgrade**: Artifactory is upgraded to Groovy 4 in version *7.101.0* (released on 25th Nov 2024 for cloud), which leads user plugins compatible with groovy 4. The promotion plugin has been updated for compatibility with Groovy 4. This upgrade may affect existing user plugins, so ensure you test your plugins after upgrading.

+
+## Contributing to Artifactory User Plugins
+Although JFrog Workers is the preferred approach, we still accept contributions for Artifactory user plugins, particularly for those who cannot migrate to JFrog Workers at the moment. Contributions should follow the guidelines specified in the [CONTRIBUTING.md](CONTRIBUTING.md) file. 
+
+To maintain a consistent and high-quality codebase, we encourage contributions to:
+- **Fixing bugs or security issues**
+- **Refactoring existing functionality for better compatibility with newer Artifactory versions**
+
+## Migrating from User Plugins to JFrog Workers
+
+If you are planning to migrate from Artifactory user plugins to JFrog Workers, follow the steps below:
+
+1. **Evaluate**: Check the list of existing user plugins and identify the functionalities that need to be migrated.
+2. **Explore Worker Samples**: Review existing [worker samples](https://github.com/jfrog/workers-sample) to understand how workers can replace your current plugin logic.
+3. **Refactor and Deploy**: Migrate the logic to a JFrog Worker and test it in your development or staging environment.
+4. **Monitor and Optimize**: Once the worker is running in production, monitor its performance and optimize as needed.
+
+Migrating to JFrog Workers allows you to leverage the benefits of cloud-native architecture, including scalability, improved security, and better maintenance.
