Sorry, this isn't quite ready yet Soon(TM)

Don't use it yet

Alternatives

Here are some alternatives in the interim. I've not actually used any, and can't make any recommendations.

Neovim only for now anyway, newish(TBD) version

Expects your openai api key in environment variable OPENAI_APIKEY - Note: IT IS NOT A FREE SERVICE! (though they do provide some starting credit)

Terrible keybinds for the functionality so far are in plugin/openai-test.lua

They are truly terrible and temporary - I've put no thought in to them
They are hardcoded for development, likely end users would put everything from plugin/openai-test.lua in their vim init.
They aren't documented, wait till they are.
