### Windows setup ###
1. Check you have Python installed, and that your system's PATH environment variable includes the path to Python. See [Using Python on Windows](https://docs.python.org/2/using/windows.html). You'll need to restart the web browser after making this change, or the browser won't pick up the new environment variable.

You'll need to restart the web browser after making this change, or the browser won't pick up the new environment variable.
2. Edit the "path" property of "ping_pong.json" to point to the location of "ping_pong_win.bat" on your computer. Note that you'll need to escape the Windows directory separator, like this: `"path": "C:\\Users\\MDN\\native-messaging\\app\\ping_pong_win.bat"`.
3. Edit "ping_pong_win.bat" to refer to the location of "ping_pong.py" on your computer.
4. Add a registry key containing the path to "ping_pong.json" on your computer. See [App manifest location ](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Native_manifests#Manifest_location) to find details of the registry key to add.
