Ref: #55311 (comment)

Documentation: https://pandas.pydata.org/pandas-docs/stable/development/maintaining.html#investigating-regressions

Looking at those instructions, they are still using setup.py . Can they be modified to reflect using meson?

Not sure if we should keep the setup.py instructions and also have meson as well - or if we should switch to meson-only.

#57917 switched to meson-only instructions, should this be closed?

[rhshadrach]

Yep - thanks @Aloqeely
