 ```
-Note that most options are overwritten (e.g. passing `ft_config = { python = false }` will mean that `alpha`, `mason`, etc. are set to true) but that `severity` is merged, so that passing `spellbad = "HINT"` won't cause `spellcap` to be nil. You can pass any of `cursor`, `iter`, `treesitter`, `false`, or `true` as options to `ft_config`. The default method is `cursor`, which iterates through the buffer with `]s`. There is also `iter`, which uses Treesitter (if available) and the Lua API. Finally, `false` disables Spellwarn for that filetype and `true` uses the default (`cursor`). *Note: `iter` doesn't show `spellcap` errors, but works well other than that. I recommend it.*

 ## Usage
 The plugin should be good to go after installation with the provided snippet. It has sensible defaults. Run `:Spellwarn enable` or `:Spellwarn disable` to enable/disable during runtime (though this will *not* override `max_file_size`, `ft_config`, or `ft_default`). To disable diagnostics on a specific line, add `spellwarn:disable-next-line` to the line immediately above or `spellwarn:disable-line` to a comment at the end of the line. To disable diagnostics in a file, add a comment with `spellwarn:disable` to the *first* line of the file.
