+## Redux
+
+There are two main store created for this app:
+
+- Cozy: store information about cozy (konnectors, accounts, settings, db)
+- Ecolyo: store all states used for this app
+
+For a better state management, combineReducers(reducers) is used to split the reducing function into seperate functions. So, each managing independent parts of the state.
+
+### Ecolyo Store Structure

+Redux-thunk middleware is configured. For now, it is used only for updating the profile.
+To update a state, a webservice method is called before trigger a state change inside the store.
