 This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 9.1.6.

+# How to start Angular
+1. open command Window and change directory to Project Path
+
+2. Run `npm install` for installing all Project Dependencies <br>
+(all Dependencies inclusive node.js will be installed, generally you could use `npm` and `yarn`, but never use both at the same time for managing the dependencies. This could cause problems.)
+
+3. Run `ng serve` for compiling and starting of the angular dev server <br> 
+  (If the port ::4200 is already in use, the ng serve will abort with a exception
+  "An unhandled exception occurred: Port 4200 is already in use. Use '--port' to specify a different port.")
+  
+4. Navigate to 'http://localhost:4200/' after successful compiling <br>
+   (** Angular Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200/ **
+    : Compiled successfully.)
+    
+4. Run `Ctrl + C` to stop Angular dev server. 
+
 ## Development server
 
 Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.

 ## Further help
 
 To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).
