Issue on page /installation/micromamba-installation.html

[dllock2814]

When i try to install micromamba on my computer using this command
Invoke-Expression ((Invoke-WebRequest -Uri https://micro.mamba.pm/install.ps1 -UseBasicParsing).Content)
I get past the enter the path to the micromamba prefix which i take the default then i get the error message
"The following argument was not expected: -p"
" Run with --help for more information."

So then i scroll down to the advanced section to manually install everything:
When i get to this line in the code it errors out since there is no folder called test and no env_win.yaml file.

and use micromamba directly

micromamba create -f ./test/env_win.yaml -y
micromamba activate yourenv

Please advise on how I can resolve these issues.

Thanks.
