+# Custom Defined Helpers
+
+In addition to the [helpers provided by Middleman](http://middlemanapp.com/basics/helpers/)
+out of the box, you can also add your [own helper methods](http://middlemanapp.com/basics/helpers/#toc_9)
+and classes that will be accessible within any controller or view automatically.
+
+You just need to define module and place in this directory.
+Example:
+
+```ruby
+# helpers/coach_helpers.rb
+
+module CustomHelpers
+  def some_method
+    # ...do something here...
+  end
+end
+```
