-        **Hi there! I'm OntoChat, your conversational assistant for collecting ontology user stories.** 🎉
-
-        I simplify the process of creating ontology user stories by combining human input with GenAI capabilities. Whether you have experience with prompt engineering or not, I'm here to guide you. By Providing predefined templates, focused questions, example answers, and refinement options, I help you generate clear, high-quality user stories.
