-This tutorial doesn't require any prior TypeScript knowledge as it uses JavaScript. If you're familiar with TypeScript you can read the [Gatsby and TypeScript guide](/how-to/custom-configuration/typescript/) to learn about typings, files, and conventions. If you want to use TypeScript we recommend going through the tutorial first and then only afterwards convert the project to TypeScript.
