LGTM, thanks.

I did not think we would remove lines that say which Python version to use for Plone 6.0. But since 6.0 is strictly speaking already out of maintenance support, or will be once 6.1 final is out, I guess this cleanup makes sense. Otherwise there is just too much information, and people will get confused.

@mauritsvanrees yup, this was one of the trade-offs between completeness and simplification. In this case, less detail is more helpful, especially in how-to guides.

@mauritsvanrees @davisagli which is preferred here, 6.1-latest or 6.1.0? I think 6.1-latest is preferred so that we don't have to update the commands for patch releases.

[davisagli]

@stevepiercy Yes, I would go with 6.1-latest

We can ignore the failed linkcheck for docutils, as sourceforge is temperamental. Let's wait for the RTD check.

This seems fine now. Thanks!
