 #### Creating your Storage
-A storage represents your database, Realm, or CoreData. The first step to start using SugarRecord is initializing the storage. SugarRecord provides two default storages, one for CoreData, `CoreDataDefaultStorage` and another one for Realm, `RealmDefaultStorage`.

 - **MainContext:** Use it for main thread operations, for example fetches whose data will be presented in the UI.
 - **SaveContext:** Use this context for background operations. The context is initialized when the storage instance is created. That context is used for storage operations.
