+# Override The Default Yarn Version
+
+When you first deploy an app to [Netlify](https://www.netlify.com/), the
+current default [Yarn](https://yarnpkg.com/) version will be locked in. This
+Yarn version will be used for future builds and deployments.
+
+You can override the default Yarn version by including the `YARN_VERSION`
+environment variable. Set it to the desired major and minor version in the app
+settings panel. The next deployment will use that new version.
