The "Instruct" node allows you to add a prompt into your flow. The prompt will generate content which can then be used in another action.
Prompt: The prompt/instruction that the AI must carry out.
Example 1: This flow will write a story and automatically create a document using the story as the document content.
Example 2: This flow will generate a story title and a story which will be emailed. The story title that is generated would then be used as the subject and the story will be used as the body of the email.
