+## The idea behind the example
+
+This example features:
+
+* An app that mixes together JavaScript and ReasonML components and functions
+* An app with two pages which has a common Counter component
+* That Counter component maintain the counter inside its module. This is used primarily to illustrate that modules get initialized once and their state variables persist in runtime

+## The idea behind the example
+
+Redux uses single store per application and usually it causes problems for code splitting when you want to load actions and reducers used on the current page only.
+
+This example utilizes [fast-redux](https://github.com/dogada/fast-redux) to split Redux's actions and reducers across pages. In result each page's javascript bundle contains only code that is used on the page. When user navigates to a new page, its actions and reducers are connected to the single shared application store.
