sorry about the bad branch name, i think i goofed up the fork and pull web flow

Thanks for the PR. I feel like there should be an easier way to do this if you're just trying to setup an instance for yourself to use. Maybe by storing a personal access token in the script properties instead of setting up a whole OAuth app? Or, are you actually trying to setup a new instance that can be used by multiple people?

oh word, that makes sense - i was just trying to document what seemed to be necessary at the current state of things for a single person.

Gotcha. I can come back later and try to make this flow easier. Thanks for the docs!
