 In the `setupPorts` function, we first subscribe to the `numActiveTodos` port. Whenever the number of active todos changes, we will run that function and log the number on the console. After that, we send two values through the `todos` port. This will add both of these into the model *and* trigger the `numActiveTodos` callback twice.
 
 
-### Notes
-
-Once the properties are initialized, they will never be used again. Changing `flags` or `ports` will do nothing. So here are two tricks that may help you out:
-
- - If you want to reinitialize your Elm component, add a different `key` to the old and new components. This way old one is destroyed and replaced by the new one.
-
- - If you want to change your ports, you should save the `ports` object into your `state` so you can mess with it later.

 So if you are interested in embedding Elm in something else, do the same trick! You can get more complete docs on embedding Elm in HTML [here](http://guide.elm-lang.org/interop/html.html) and JavaScript interop [here](http://guide.elm-lang.org/interop/javascript.html). Let the community know if you make something!

+# Advanced Usage
+
+Once the Elm component is initialized, changing the `flags` and `ports` properties will do nothing. So here are some tricks that may help you out:
+
+ 1. If you want to reinitialize your Elm component, add a different `key` to the old and new components. This way old one is destroyed and replaced by the new one.
+ 2. If you want to mess with ports, you can save the `ports` object into your `state` and access it later.
+ 3. This package is super simple. Fewer than 20 lines. Check out the implementation and do it different if you want!
