+# Please upgrade Node [![](http://img.shields.io/npm/dm/please-upgrade-node.svg?style=flat)](https://www.npmjs.org/package/please-upgrade-node) [![Build Status](https://travis-ci.org/typicode/please-upgrade-node.svg?branch=master)](https://travis-ci.org/typicode/please-upgrade-node) [![npm](https://img.shields.io/npm/v/please-upgrade-node.svg)](https://www.npmjs.com/package/please-upgrade-node)
+
+> :information_desk_person: show a message to your users to upgrade Node instead of a stacktrace 
+
+It's common for new Node users to miss or not understand engines warning when installing a CLI. This package displays a beginner-friendly message if their Node version is below the one expected.
+
+```sh
+$ node -v
+0.12
+
+$ modern-cli
+modern-cli requires at least version 6 of Node, please upgrade
+```
+
+## Support
+
+If you like this project, you can support me on [GitHub Sponsors](https://github.com/users/typicode/sponsorship)
+
+## Usage
+
+```sh
+npm install please-upgrade-node
+```
+
+Add `please-upgrade-node` at the top of your CLI
+
+```js
+#!/usr/bin/env node
+const pkg = require('./package.json')
+require('please-upgrade-node')(pkg) // <- Must run BEFORE requiring any other modules
+
+// ...
+```
+
+Set in your `package.json` the required Node version
+
+```js
+{
+  "engines": {
+    "node": ">=6"
+  }
+}
+```
+
+__Important__: `>=` is the only operator supported by `please-upgrade-node` (e.g. `>=6`, `>=6.0`, `>=6.0.0`).
+
+## Options
+
+You can set custom `exitCode` and `message` function if needed
+
+```js
+pleaseUpgradeNode(pkg, {
+  exitCode: 0, // Default: 1
+  message: function(requiredVersion) {
+    return 'Oops this program require Node ' +  requiredVersion
+  }
+})
+```
+
+__Important__: to keep `message` function compatible with older versions of Node, avoid using ES6 features like `=>` or string interpolation.
