I have a brand new hub to which I want to add new driver. I forgot how to add it. It is a Shabbat/holiday scheduler.

What you're describing sounds a lot more like an app than a driver. To add custom app code, navigate to Apps Code (on the left), click New App, copy/paste the code into the editor (or click Import and provide a URL to "raw" code), and then click Save. If you do not see Apps Code, click the arrows next to Developer Tools to expand that section.

Either my instructions or @csteele’s instructions will work. His are probably more straightforward, with fewer steps, than the thread I linked. The thread I linked, though, is more general, and will install any app.
