Creating a new Julia environment is perhaps not so clear

[HannoSpreeuw]

The REPL paragraph in the documentation says:

If you want to experiment with things, try to create a new environment 
in an empty folder and add CarboKitten as a dev dependency

Perhaps it is not so clear for a lot of users how to create a new environment in Julia.

Or you could consider that not part of this documentation and people should figure it out using the Julia documentation.

Reading this, it is not clear to me why one should do it. After all, it is a CarboKitten documentation, not a Julia course. So I think it should stick to commands needed to run CarboKitten.
So I would rephrase this:

Additionally you should learn how to work with Julia packages.

to

Running CarboKitten will require to load other dependencies, so please consult the documentation on Julia packages to learn how.

Writing "you should learn to" may come across as a bit patronizing, and our users will be already humiliated enough, I think.
