Getting a "can't verify the developer" warning?

If you see a warning on first launch, go to System Settings > Privacy & Security and click "Open Anyway". Open source software usually isn't signed with an Apple developer certificate, which is normal.

Clicking "Download" takes you to a source confirmation page first; the download starts after confirmation.
