 The `ListMonitor` monitors changes to a list of `NSManagedObject` instances. Observers that implement the `ListObserver` protocol may then register themselves to the `ListMonitor`'s `addObserver(_:)` method:
-
+ ```
 let monitor = CoreStore.monitorList(
     From(MyPersonEntity),
     Where("title", isEqualTo: "Engineer"),
     OrderBy(.Ascending("lastName"))
 )
 monitor.addObserver(self)
-
+ ```
 The `ListMonitor` instance needs to be held on (retained) for as long as the list needs to be observed.
 Observers registered via `addObserver(_:)` are not retained. `ListMonitor` only keeps a `weak` reference to all observers, thus keeping itself free from retain-cycles.
 
 Lists created with `monitorList(...)` keep a single-section list of objects, where each object can be accessed by index:
-
+ ```
 let firstPerson: MyPersonEntity = monitor[0]
-
+ ```
 Accessing the list with an index above the valid range will throw an exception.
 
 Creating a sectioned-list is also possible with the `monitorSectionedList(...)` method:
-
+ ```
 let monitor = CoreStore.monitorSectionedList(
     From(MyPersonEntity),
     SectionBy("age") { "Age \($0)" },

 Objects from `ListMonitor`s created this way can be accessed either by an `NSIndexPath` or a tuple:

 let indexPath = NSIndexPath(forItem: 3, inSection: 2)
 let person1 = monitor[indexPath]
 let person2 = monitor[2, 3]

 In the example above, both `person1` and `person2` will contain the object at section=2, index=3.

 ## What CoreStore does better:

- Heavily supports multiple persistent stores per data stack, just the way *.xcdatamodeld* files are designed to. CoreStore will also manage one data stack by default, but you can create and manage as many as you need.
- Incremental Migrations! Just tell the data stack the sequence of model versions and CoreStore will automatically use incremental migrations if needed on stores added to that stack.
- Ability to plug-in your own logging framework
- Gets around a limitation with other Core Data wrappers where the entity name should be the same as the `NSManagedObject` subclass name. CoreStore loads entity-to-class mappings from the managed object model file, so you are free to name them independently.
- Provides type-safe, easy to configure observers to replace `NSFetchedResultsController` and KVO
- Exposes API not just for fetching, but also for querying aggregates and property values
- Makes it hard to fall into common concurrency mistakes. All `NSManagedObjectContext` tasks are encapsulated into safer, higher-level abstractions without sacrificing flexibility and customizability.
- Exposes clean and convenient API designed around Swift’s code elegance and type safety.
- Documentation! No magic here; all public classes, functions, properties, etc. have detailed Apple Docs. This README also introduces a lot of concepts and explains a lot of CoreStore's behavior.

-### Incremental migrations
+### Progressive migrations
 By default, CoreStore uses Core Data's default automatic migration mechanism. In other words, CoreStore will try to migrate the existing persistent store to the *.xcdatamodeld* file's current model version. If no mapping model is found from the store's version to the data model's version, CoreStore gives up and reports an error.

 The `DataStack` lets you specify hints on how to break a migration into several sub-migrations using a `MigrationChain`. This is typically passed to the `DataStack` initializer and will be applied to all stores added to the `DataStack` with `addSQLiteStore(...)` and its variants:
