How to check if Google Tag Manager is installed properly (and works properly)

After you have installed Google Tag Manager (but before you create your first tag), you should make sure that GTM is installed properly. There are multiple ways to do that and in this video I will show you some of them.

To name a few:
Check the source code of your website
Enable Google Tag Manager Preview and Debug mode
Check Google Tag Assistant.
But this list is not done yet. More are explained in this video.
