+* **First Message**: Specify the initial spoken message when entering the node. This configuration is helpful if developers want the agent to speak first without waiting for user to say something.
 
-The prompt is the most important part of the Conversation Node. Building reliable and high-quality voice agents heavily depend on the quality of the prompt supplied.
+* **Prompt**: Provide detailed instructions guiding agent responses and conversation direction, including response style and content. The prompt is the most important part of the Conversation Node. Building reliable and high-quality voice agents heavily depend on the quality of the prompt supplied.
 
-Extract Variables lets users gather/extract variables from a conversation. These variables can be used as dynamic variables for the rest of the workflow via liquid syntax `{{ variable_name }}`. 
+* **Model/Voice/Transcriber Settings**: Individually configure the AI model, voice, and transcription services per node. This is similar to configuring Single Prompt Assistants.
 
-Variables can be configured by:
-- Defining variable name and data type (String, Number, Boolean, Integer)
-- Writing a clear extraction prompt (a description of the variable to help determine how/what data to extract)
-- Setting enums for String-type variables to constrain values (to map to a specific set)
