Hi @fnattino, would you like to take a look at this PR? thanks!

Hi @rogerkuou, apologies with the delay with this.

I think it looks great, I have left a few suggestions. I think we should fix the links to point to the main branch of the carpentries incubator repo, feel free to consider or discard all other feedback and merge afterwards!

[fnattino]

Also pinging @rbavery and @Morrizzzzz - we are updating the setup instructions to useuv as default with a fallback on conda, it will hopefully make setup of participants even easier!

Hi @fnattino , I apated most of your comments, apart from the two regarding Powershell home dirs. Could you please have another look?

[fnattino]

Just found a typo, feel free to merge afterwards! Thanks a lot for this!
