+# Pluralize Helper
+
+Orchestra provides a helper to pluralize words when appropriate.
+
+In order to make it work you need to have a singular and plural strings defined in your locale
+```js
+var enGB = {
+  'en-GB': {
+    'translation': {
+      'day': 'day',
+      'day_plural': 'days'
+    }
+  }
+};
+```
+
+You would use this helper in your handlebars template like so:
+```js
+
+{{pluralize "day" 0}}  // renders 'days'
+{{pluralize "day" 1}}  // renders 'day'
+{{pluralize "day"}}    // renders 'day' (default behaviour)
+
+```
