• You can generate a key/cert with: openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 365
• If Chrome complains about an invalid cert, you can type thisisunsafe on that page and Chrome will let you proceed
• go to https://localhost:4443/index.html

Install the Chrome extension

• Go to chrome://extensions and enable Developer mode.
• Load unpacked and select the folder containing this manifest.json

Note the extension ID in the webpage at index.js. This ID is generated by Chrome when you install a local extension so replace this string with the ID from the chrome://extensions page.

To get it working with your own website, update the externally_connectable setting in manifest.json so that your page can communicate with the extension.
