Install in three steps

1. For automatic updates, open chrome://flags/#extension-mime-request-handling, choose Always prompt for install, relaunch Helium, then install the signed extension.
2. Create a vault in the extension using this server URL and the server's setup token. Save the sync code it gives you.
3. Install the extension on each other Mac or Windows device and pair it using that sync code. Keep both tokens and codes private.
