# You should insert this script into your PowerShell Profile script so it exists in every session

# Fun fact: This script was mostly generated by ChatGPT by giving it the bash version of the output 
# from `github-copilot-cli alias -- "$0"` with a few fixes from me

To support multi line commands, add -Raw to Get-Concent.

I've updated the script with your suggestion @qqii, thank you!

@MattJeanes
Been trying to use Copilot CLI for almost a month now and I just came across this and it worked!
Thank you!

Thanks Matt, it's working fine 👍
