Which package to download?

If you are running the official Arduino IDE, download ArduinoJson-v5.3.0.zip.
You can also use the library manager from the IDE, it will download the library for you.

If you are running an alternative IDE (like Energia or Stino), download ArduinoJson-v5.3.0-old-layout.zip
This package has the legacy library layout that was supported by older versions of the Arduino IDE.
