+## The Basic
+
+Angular serves the **index.html** in the `src` directory and loads the components from the `src/app` directory.
+
+The scafolding creates a root-component which is loaded into the index.html on the `<app-root></app-root>`-Tag.
+
+In the `@Component` we find a `selector` with the value of `<app-root></app-root>`. With this selector, Angular is able to replace in the index.thml on the `<app-root></app-root>`-Tag with the content in the app.component.html.
+
+When the app is builded, the angular cli will inject at the bottom a bundle of *.js files which is needet to run the app.
+
+`main.ts` is the file which will be executet at the beginning.
+
+
+<img src="../img/ngmodule.png" alt="ngmodule" width="800"/><br>
+<img src="../img/component.png" alt="component" width="800"/>
+
+
+Angular's main ideas is to build components to build an app. Each Component has it's own template (html), maybe it's own style (CSS) and more important it's own business logic.
+Components can be reused in multiple parts or the application.
