+### Le Storage
+
+LeStorage is used to store objects into json files, and it can also be used to synchronize those objects to a django server properly configured.
+
+Here are the most important classes:
+- StoredCollection: stores object of one class in a json file
+- SyncedCollection: stores object of one class in a json file and synchronizes changes with the server
+- ApiCallCollection: provision HTTP calls and tries to execute them again
+- StoreCenter: The central class to manages all collections through Store instances
