@Mykle1 - thanks for this guide. I promise I’ve studied it through and read the additional helpful comments that other contributors have made. However, I’ve having trouble adding the MMM-PrayerTime module to config.js. When I add the module and MM restarts, it shows blank and an error telling me to create a config file. Grateful for pointers on where I’m going wrong (please see code below. I’ve hidden any personal information). Thanks.

To note that without the entry to the MMM-PrayerTime module added to config.js Magic Mirror runs fine with the other modules.
