-  - Fully automated C/CD pipeline to AWS for provisioning serverless infrastructure using GitHub actions.
 - Have full visibility into what the tweaks do as you enable them.
 - Ability to revert applied scripts

+- Powered by **TypeScript**, **Vue.js** and **Electron** 💪
   - and driven by **Domain-driven design**, **Event-driven architecture**, **Data-driven programming** concepts.
 - Application uses highly decoupled models & services in different DDD layers.

   - **Presentation Layer**
-    - Consists of Vue.js components & UI stuff.
+    - Consists of Vue.js components and other UI-related code.
+    - Desktop application is created using [Electron](https://www.electronjs.org/).
     - Event driven as in components simply listens to events from the state and act accordingly.
   - **Application Layer**
     - Keeps the application state
       - The [state](src/application/State/ApplicationState.ts) is a mutable singleton & event producer.
     - The application is defined & controlled in a [single YAML file](src/application/application.yaml) (see [Data-driven programming](https://en.wikipedia.org/wiki/Data-driven_programming))
