+# Create Bootstrapped Apps With Yarn
+
+The [`yarn` cli](https://yarnpkg.com/lang/en/docs/cli/) comes with a
+[`create`](https://yarnpkg.com/blog/2017/05/12/introducing-yarn/) command
+that is a convenience command for generating bootstrapped apps that follow
+the `create-<name>-app` convention.
+
+Want to create a React.js app using
+[`create-react-app`](https://github.com/facebookincubator/create-react-app),
+invoke the following command:
+
+```
+$ yarn create react-app my-app
+```
+
+Don't already have a particular package globally installed? `yarn create`
+will install it for you. For instance, the following command with install
+and use [`create-vue-app`](https://github.com/egoist/create-vue-app):
+
+```
+$ yarn create vue-app my-other-app
+```
