+**Store** or **Update** instances of classes to MongoDB:
 DbDoc extends your class with the following methods:
 
-- `.save()` will save (or update) the object you call it on only. Any referenced non-savable objects will not get stored.
+- async `.save()` will save (or update) the object you call it on only. Any referenced non-savable objects will not get stored.
-- `.saveDeep()` does the same like `.save()`.
+- async `.saveDeep()` does the same like `.save()`.
   In addition it will look for properties that reference an object
   that extends DbDoc as well and call .saveDeep() on them as well.

-DbDoc exposes a static method that allows you specify a filter to retrieve a cloned class of the one you used to that doc at some point later in time. Yes, let that sink in a minute :)
+DbDoc exposes a static method that allows you specify a filter to retrieve a cloned class of the one you used to that doc at some point later in time:
+
+* static async `.getInstance({ /* filter props here */ })` gets you an instance that has the data of the first matched document as properties.
+* static async `getInstances({ /* filter props here */ })` get you an array instances (one instance for every matched document).

+**Delete** instances from MongoDb:
+smartdata extends your class with a method to easily delete the doucment from DB:

-So you can just call `.getInstance({ /* filter props here */ })`.
 
 ## TypeScript
 
 How does TypeScript play into this?
 Since you define your classes in TypeScript and types flow through smartdata in a generic way
 you should get all the Intellisense and type checking you love when using smartdata.
-smartdata itself also bundles typings.
+smartdata itself also bundles typings. You don't need to install any additional types for smartdata.
-So you don't need to install any additional types when importing smartdata.
