+A pattern's `use()` method will load a FreeSewing plugin.
+Plugins are a way to extend a pattern's functionality, and can be
+loaded both at build-time and at run-time. This method only applies
+to run-time plugins. For more details, refer to [the plugin guide](/guides/plugins/).
+
+<Note>This method is chainable as it returns the Pattern object</Note>
+
+## Pattern.use() signature
+
 ```js
 Pattern pattern.use(object plugin)
 ``` 
-Loads a freesewing plugin. This method is chainable.

+See [the plugin guide](/guides/plugins/) for details on how to structure
+you plugin object.
