GitHub Pages?

I'd like to suggest making a GitHub Page for this project that runs write-good on a textarea the user can type in. I'd like to recommend this for "normal people" (i.e. non-developers), and I don't want to be like "first, get this 'node' thing, then open command prompt."

No files, tests, or entry points are named. Start by reviewing how write-good can be exposed in a browser and how this project could be published with GitHub Pages. Done means a public page provides a textarea, runs write-good on its contents, and shows the results without requiring Node or a command prompt.
