Example Saltstack at getstarted/ssh/connect.html is incomplete

https://docs.saltstack.com/en/getstarted/ssh/connect.html

If using Saltfile as suggested on the page, salt-ssh will not function because of numerous permissions issues. There are a lot of suggestions in the guide and in error messages to fix those with sudo, but sudo is not an option when running as non-root.

I had to check these additional sources to at least make that example work
https://github.com/saltstack/salt/issues/8062
https://docs.saltstack.com/en/latest/ref/configuration/nonroot.html

Saltfile

salt-ssh:
  config_dir: ./etc
  roster_file: ./roster
  ssh_log_file: /tmp/salt-ssh.txt

./etc/master (not sure about file_roots though)

file_roots:
  base:
      - .
state_verbose: False
cachedir: /home/non7top/sls/cache
pki_dir: /home/non7top/sls/pki

Most troublesome part was to identify where to put cachedir after I found out about it, I tried cachedir and ssh_cachedir in Saltfile without any effect.

There is also a discrepancy where Saltfile accepts relative paths with ./, while ./etc/master converts ./ to /. Not sure if that is a bug worth submitting.

Setup

python3 -m venv salt
. salt/bin/activate
pip install --upgrade pip wheel
pip install salt-ssh

Steps to Reproduce Issue

Start with getstarted/ssh/connect.html and compare its Saltfile example with the reported ./etc/master configuration and the nonroot configuration guide. Reproduce the guide using the listed Python virtual-environment setup and salt-ssh command. Done means the documented example works for a non-root user and clearly explains the required cache and path settings.
