+# Jjodel Code of Conduct
+
+## Short Version
+We, as members, contributors, and maintainers of **Jjodel**, pledge to foster an open, welcoming, and harassment-free environment for everyone, regardless of age, ability, gender identity or expression, ethnicity, education, experience, nationality, personal appearance, race, religion, or sexual orientation.
+
+We aim to build a collaborative and inclusive community where learning, research, and innovation in model-driven engineering can thrive.
+
+If you experience or witness behavior that violates this Code of Conduct, please contact:

+
+## Our Standards
+
+### Positive Behaviors
+* Be respectful, patient, and considerate.  
+* Welcome different viewpoints and experiences.  
+* Offer and accept constructive feedback gracefully.  
+* Focus on collaboration, learning, and improvement.  
+* Acknowledge and credit the work of others.  
+
+### Unacceptable Behaviors
