Docs for 4.x

I’m using 4.0 and I just can’t find any source of documentation.
Everything just points to https://docs.mitmproxy.org/stable/ that has a link to https://mitmproxy.org/ that in turn points to the first page.
Examples for previous versions do not work and even finding the doc to use a single command is a pain.
Is there a page with all the commands working in 4.0, maybe with some examples?
Thanks
