Maestro in Home Assistand

Dear

I am a new user of Home Assistant in Rasberry pi. I still have a lot to learn. Today I spent a whole day installing the repository Maestrogateway https://github.com/Chibald/maestrogateway . I did not succeed. I try to follow your instructions on the website closely, but I keep getting stuck.

When working with a terminal it does not execute this file “bash install”.
When I use docker, the version of docker-compose.yml is higher than version 2 and it doesn’t work.

What am I doing wrong and what can I do?

How can I install “Maestro Gateway” on my “Home Assistance”?
I would greatly appreciate it if you could put me on my way.

With best regards
Koen
