  • Add new public functions/methods/classes to doc/api/index.rst.
  • Write detailed docstrings for all functions/methods.
  • If wrapping a new module, open a 'Wrap new GMT module' issue and submit reasonably-sized PRs.
  • If adding new functionality, add an example to docstrings or tutorials.
  • Use underscores (not hyphens) in names of Python files and directories.

Just one very minor suggestion, but otherwise I think it's documented really well!

Inplace assignment operators like ``*=`` don't create new instances, so the
properties are still kept:

>>> grid *= 2.0
>>> grid.gmt.registration, grid.gmt.gtype
(0, 1)

Interesting, good to know that in-place assignment preserves the registration and gtype information!

Technically xarray accessors are not just about setting properties/attributes. You may need to change this sentence if the .gmt.imshow() function at #2372 is added to this accessor class.

Will rephrase this sentence in PR #2372.
