Where to find the tutorials for the forum badges "Certified" and "Licensed"?

Where can we find these tutorials?
– Completed our new user tutorial
– Completed our advanced user tutorial

I am realy curious about them, though have no idea where to find them.

The user adelaidenx told me how find the tutorials.

You just need to respond the discobot’s greeting message with following commands to activate the interactive tutorials:
certified: @discobot start tutorial
licensend: @discobot start advanced tutorial

@Docker: It would be helpfull if the generic description for the badges would indicate their context.
If I’d known the context, I would never had spend a second on searching or doing them.
Instead of checking your docker knowledge level, both tutorials teach you how to use Discord properly.
