# Importing Yarn Files

There are two important kinds of files you'll use when working with Yarn Spinner for Unity:

* [Yarn Scripts](https://docs.yarnspinner.dev/2.2/using-yarnspinner-with-unity/importing-yarn-files/yarn-scripts) are files that contain your written dialogue.
* [Yarn Projects](https://docs.yarnspinner.dev/2.2/using-yarnspinner-with-unity/importing-yarn-files/yarn-projects) are files that link all of your scripts together, and are used by the Dialogue Runner.
