SCAFFOLDING

The scaffolding of the code in the repository was done with

ionic start ionic4-start-a3 blank --type=angular
cd ionic4-start-a3
ionic generate service services/wordsData
ionic generate page pages/choose-mode
ionic generate page pages/learn-mode
ionic generate page pages/practice-mode
ionic generate page pages/wordlist
ionic generate page pages/settings
ionic generate page pages/about

The genereated code is in the src directory and had to be configured. Such as for example changeing the header of the pages files (home page excluded) to

<ion-header>
  <ion-toolbar color="primary">
    <ion-title>...</ion-title>
    <ion-buttons slot="start">
      <ion-back-button></ion-back-button>
    </ion-buttons>
  </ion-toolbar>
</ion-header>

The header of the page home.page.html is

<ion-header>
    <ion-toolbar color="primary">
    <ion-buttons slot="end">
        <ion-button routerLink="/about">
            <ion-icon name="information-circle"></ion-icon>
