+## An example of using `react-async` with `react-router` (built with parcel)
+
+The idea was to make fetching data for pages (components) configurable in a declarative way
+
+```
+    <Router>
+        ...
+        <ApiRouter path="/repositories" fetchUrl='https://api.github.com/repositories' component={RepositoriesComponent} />
+    </Router>
+```
+
+## Running the example
+
+```
+  npm install
+  npm run start
+```
+and then goto [http://localhost:1234](http://localhost:123)
