I wouldn't put that under API reference as it's not an API reference.

Good catch, I would argue to rename API reference to just Reference, or Reference guides then :)

If we stick to diátaxis guidelines, it is definitely more information-oriented than understanding-oriented, so it does not make sense to include it in the explanatory section.

Reference guides looks good!
