From the readme:
> Org grammar for tree-sitter. It is not meant to implement emacs' orgmode parser, but to implement a grammar that can usefully parse org files to be used in neovim and any library that uses tree-sitter parsers.
This grammar is in active development and is being used by nvim-orgmode/orgmode [1], a org-mode neovim plugin.
