-h3. How Caching Works
+h3. Assets Cache Store
-Sprockets uses the default Rails cache store to cache assets in development and production.
+If you will not configure assets cache store, your application's cache store will be used to cache assets in development and production.
-TODO: Add more about changing the default store.
+You always can access your application's cache by calling +Rails.cache+.
+Default assets cache store can be changed to something else, like memory store:
+config.assets.cache_store = :memory_store
+All the assets cache store parameters should be passed in the same way like for application's cache store.
