Extension - Record Tags

“It is important to note that your Radiant instance MUST define the
models you plan on accessing.” This is sentence from this extension’s
tutorial. But what exactly I have to do?

Thanks for help.

I don’t see the tutorial you are talking about. Link, please?

It means that if Radiant is not yet aware of some model (another
database table for example) you’ll need to create an extension that
includes those models.
