 # About
 
-**kApp** is an demonstration application based on the [Kalisio Development Kit](https://kalisio.github.io/kdk/) (**KDK**) available now as a single package [@kalisio/kdk](https://www.npmjs.com/package/@kalisio/kdk).
-
-::: tip
-For a deeper understanding of the overall structure, please refer to our [application template](https://kalisio.github.io/skeleton).
-:::
+The **kApp** (i.e. KDK-based Application) is a demonstration application created from the [skeleton](https://kalisio.github.io/skeleton/), which includes all the necessary boilerplate that you need to get started building your application with the [Kalisio Development Kit](https://kalisio.github.io/kdk/).
+
+It also includes the minimum viable set of features to start:
+* a [basic application layout](https://kalisio.github.io/kdk/api/core/components.html) including side navigation, application bar, right panel and various widgets
+* ready-to-go [user authentication services](https://kalisio.github.io/kdk/api/core/services.html#users-service) and [screens](https://kalisio.github.io/kdk/api/core/components.html#authentication),
+* a [basic service](https://kalisio.github.io/kdk/api/core/application.html) to create/remove documents in database,
+* a [basic collection activity](https://kalisio.github.io/kdk/api/core/mixins.html) listing documents using either [a list, a grid or a table](https://kalisio.github.io/kdk/api/core/components.html#collections),
+* a [basic editor](https://kalisio.github.io/kdk/api/core/components.html#editors) to fill document properties when creating a new document.
