Nextcloud setup

I’m following this guide to setup Nextcloud SWAG setup -

Question, are you expected to change these fields to increase security? In this guide it is not very clear which fileds you should change.

  - MYSQL_ROOT_PASSWORD=mariadbpassword
  - TZ=Europe/London
  - MYSQL_DATABASE=nextcloud
  - MYSQL_USER=ncuser
  - MYSQL_PASSWORD=ncpassword

Yep those are example values, so it’s recommended you change them to something more unqiue but make sure you make note of which ones you do change so that you can use the correct one further in the setup.
