Gatsby “Hello Dev” Plugin

I originally set out to create a plugin that would replicate the experience you get when opening your dev tools on a site like KeyBase:

keybase greeting

However, after trying a few things, it ended up not being possible to get this particular experience using a Gatsby plugin. Hence, this plugin is now an empty shell.

You can do it with html.js. See here for more explicit instructions on adding a top-level HTML comment to your Gatsby site.
