Installation instructions update for poetry

[ejm4567]

Can the install instructions be updated for poetry?

I am trying to install and run the examples in Chapter 12 using poetry.
I've added a section tool.poetry to pyproject.toml in the Chapter 12 cloned git repo for rmux_server

Typing poetry install after adding the missing section tool.poetry yields no error, but then doing the following:
cd rmux_server python3 tcp_server.py

yields nothing running.

I've not used poetry before, so apologies if this is simple.

Do you see any errors when starting the server? Does It work when installing the package directly with pip?

In the command line that you show, there is a missing && after the cd:

cd rmux_server && python3 tcp_server.py

Do you know if this is a typo in the comment? Otherwise, the server is not started.
