## Use the whole document as context

1. Select **Write custom prompt** and write a prompt. We are writing a thank you note.
2. Write all the necessary context in your Google document if there is none present yet.
3. Select **Use selection or document as context** and click **Submit**.

GPT for Docs adds the context of your document to the prompt, enabling the model to generate a note based on that context.
