Related, the first item in the About menu on macOS using the provided binary says, "About ElectronReact". I believe https://github.com/DocNow/hydrator/blob/master/app/main.development.js#L112 is where the value resides. I would submit a PR but cannot build and test per #9.

Maybe some context should be provided to University of Maryland, e.g., copyright: "Copyright © 2020 University of Maryland" in electron-builder.yml?

For providing additional data about the app, you might also consider the approach from @N0taN3rd's Electron version of WAIL:

...implemented here.

I am still hunting around for an Electron app that specifies URL in the about window if the single option in the menu is preferable.
