how can i make a new custom simulated environment in mars

Sorry for asking a question.

i want to make a new simulated environment in mars

But the official documentation is
Detailed but no way to make new environment

I read this but… it is difficult to create a new
Simulation environments | MARS | 1.0.1 (unity3d.com)

There is no way to make it on the unity learn site either.

Is there a site I can refer to?

I will learn before the answer is posted here through tutoring, etc., but I left this post because I thought other people would ask the same question in the future.

thank you

This should be covered in the newer docs:
