+> Boilerplate to kickstart creating a Node.js command-line tool
+
+This is what I use for [my own command-line tools](https://www.npmjs.com/~sindresorhus).
+
+Also check out [`node-module-boilerplate`](https://github.com/sindresorhus/node-module-boilerplate).
+
+## Getting started
+
+**Click the "Use this template" button.**
+
+Alternatively, create a new directory and then run:
+
+```
+$ curl -fsSL https://github.com/sindresorhus/node-cli-boilerplate/archive/master.tar.gz | tar -xz --strip-components=1
+```
+
+There's also a [Yeoman generator](https://github.com/sindresorhus/generator-nm).
