Can I take this issue up? @Zac-HD

[priyanshu-panwar]

@Pierre-Sassoulas can you give me a short guidance on how to start contributing. I have already done the setup and followed the contribution page. I just wanted to have a guidance on start so I can proceed on my own.
Really Grateful.
Thank You

[Pierre-Sassoulas]

Do you have a particular question, I'm not sure what to tell you that is not already in the contributor guide ?

I ran pytest --fixture --help using python 3.11 and same pytest version in linux and it's working fine, are there more details you can provide to help better?
