@@ -27,7 +27,13 @@ There are 2 points, which I declare as  exceptions:
 - the use of JsDoc[^4], because it improves the readability, most IDE support it completely lives inside of comments. It's plain and simple, therefore worth it. 
 - the implementation of `Progressive Web Apps (PWA)`[^5]. Although it's a native browser feature, platform and browser conditions are lacking, to say the least. So I see why one might consider this as a violation of 'keep it as simple as possible'. Nonetheless I wanted to give users the possibility to install this app, if by chance the environment supports it. If it becomes to much of a hassle to keep up with the state of PWA, then I am going to drop it at once.
