Documentation enhancement

Issue in /src/pages/before-administer/models-api.md

Would it be possible to get better documentation around the taxonomy options?

Such as expanding on this with examples:

Also when updating the global block list, it wasn't clear to me that the PUT request overwrites the whole list rather than appending it.

Start with /src/pages/before-administer/models-api.md and review the taxonomy options and global block list sections. Expand the taxonomy documentation with examples and clearly state that the PUT request replaces the entire global block list rather than appending to it.
