# Using an External prompts.txt File with PromptFoo

The main [Quickstart Guide (README)](./README.md) shows how to run PromptFoo using prompts written directly inside the `promptfooconfig.yaml` file. That's great for quick tests or small projects.

But if you have **lots of prompts**, or want to **easily swap them in and out**, it's better to store them in a separate file like `prompts.txt`.

This guide shows how to do that.
