+## INSTALL
+
+ npm install babel-plugin-source-map-support
+
+## SYNOPSIS
+
+`$ cat test.js`
+
+```javascript
+
+import foo from 'foo';
+import bar from 'bar';
+
+test();
+```
+
+`$ babel test.js`
+
+```javascript
+'use strict';
+
+var foo = require('foo');
+var bar = require('bar');
+
+test();
+```
+
+`$ babel --plugins source-map-support test.js`
+
+```javascript
+'use strict';
+
+require('source-map-support/register');
+
+var foo = require('foo');
+var bar = require('bar');
+
+test();
+```
+
+## DESCRIPTION
+
+This is a [Babel](https://www.npmjs.com/package/babel) [plugin](https://babeljs.io/docs/advanced/plugins/)
+which prepends a statement equivalent to the following to source files:
+
+```javascript
+require('source-map-support/register');
+```
+
+Note: this module doesn't install the [source-map-support](https://www.npmjs.com/package/source-map-support)
+module. That should be installed separately:
+
+ npm install source-map-support --save
