# Greeting Greeting is crucial because it precisely defines how the character will interact and in what style. The first message in the greeting should be relatively long, ensuring subsequent character replies are not too short. * You can also use asterisks \*\* to describe the character’s actions. * Variables like {char} and {user} are supported in the greeting. Always use these variables instead of pronouns to achieve better reply quality. * If you want the character's reply in the welcome message to include an image, you can use Markdown syntax. For example: ``` ![Image Name](Image URL) ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://book.rochat.ai/rochat_book_en/how-to-create-a-group-scene-on-rochat/greeting.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
