Documentation update

[damms005]

For folks like us that have never used Vercel before until we encounter this awesome Hazel project, the sentence in the README that reads You only need to click a button is really confusing because after clicking the supposed Deploy button and setting everything up, it is required to still click the dropdown that reads PROMOTE TO PRODUCTION on the Vercel dashboard for the project.

The You only need to click a button phrase is indeed correct and aptly describes the ease of deployment. However, I want to suggest that somewhere in the README, the PROMOTE TO PRODUCTION step should be mentioned too, to save debug time for Vercel-newbies like myself.

Awesome project, thanks a lot!

yes, documentation wasn't clear on this. have to stumble on this before I knew there wasn't actually an error as it fails to run till I promote it to production. thanks
