 ### Tree-sitter parsers [WIP]
 
+- One workflow periodically generates the [tree-sitter-parsers.json](./tree-sitter-parsers.json)
+  file, using nvim-treesitter as a source.
+- Another workflow uses that file as a matrix input, to generate
+  rockspecs (that use [`luarocks-build-tree-sitter-parser`](https://github.com/nvim-neorocks/luarocks-build-treesitter-parser))
+  and publishes them to luarocks.org.

-> The [tree-sitter-parsers.json](./tree-sitter-parsers.json) file is
-> generated by [a github workflow](./.github/workflows/update-ts-parsers.yml).
+> Any tree-sitter parser rockspecs that cannot be built and installed by the workflow
+> are not uploaded to luarocks.org.
