+* [Jmix Documentation](https://docs.jmix.io)
+* [Online Demo Applications](https://www.jmix.io/live-demo)
+* [Jmix AI Assistant](https://ai-assistant.jmix.io) (also available in the **Jmix AI** tool window of IntelliJ IDEA)
+
+## Development
+
+- [Setup](https://docs.jmix.io/jmix/setup.html) your development environment.
+- [Open](https://docs.jmix.io/jmix/studio/project.html#opening-existing-project) the project in the IDE.
+- If you want to use AI agents to develop the application, check out the [Jmix AI Agent Guidelines](https://github.com/jmix-framework/jmix-agent-guidelines) repository.
+
+## Running
+
+To start the application, use the **${project_projectPrintableName} Jmix Application** run configuration in your IDE, or run the following command in the project root directory:
