 The Helper method is included automatically, so you can use it immediately.
 
 ```erb
-<div class="<%= classNames('foo') %>">Hello World</div>

 <%# <div class="foo">Hello World</div> %>
 ```
 
-The `classNames` method takes any number of arguments which can be a string or hash.
+The `class_names` method takes any number of arguments which can be a string or hash.
 The argument `'foo'` is short for `{ foo: true }`. If the value associated with a given key is falsy, that key won't be included in the output.
 
 ```js
-classNames('foo', 'bar'); // => 'foo bar'
-classNames('foo', { bar: true }); // => 'foo bar'
-classNames({ 'foo-bar': true }); // => 'foo-bar'
-classNames({ 'foo-bar': false }); // => ''
-classNames({ foo: true }, { bar: true }); // => 'foo bar'
-classNames({ foo: true, bar: true }); // => 'foo bar'
+class_names('foo', 'bar'); // => 'foo bar'
+class_names('foo', { bar: true }); // => 'foo bar'
+class_names({ 'foo-bar': true }); // => 'foo-bar'
+class_names({ 'foo-bar': false }); // => ''
+class_names({ foo: true }, { bar: true }); // => 'foo bar'
+class_names({ foo: true, bar: true }); // => 'foo bar'
 
 // lots of arguments of various types
-classNames('foo', { bar: true, duck: false }, 'baz', { quux: true }); // => 'foo bar baz quux'
+class_names('foo', { bar: true, duck: false }, 'baz', { quux: true }); // => 'foo bar baz quux'
 
 // other falsy values are just ignored
-classNames(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'
+class_names(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'
 ```
 
 Arrays will be recursively flattened as per the rules above:
 
 ```js
 var arr = ['b', { c: true, d: false }];
-classNames('a', arr); // => 'a b c'
+class_names('a', arr); // => 'a b c'
 ```
