Prerequisites for receiving WP10 preview

[anon(8574867)]

What do I need installed on my phone to ensure I receive the WP10 preview content when it becomes available? Do I still need the "Preview For Developers" app installed and enabled (which was required for the 8.1 updates)? Do I need the "Windows Insider" app installed and do I need to keep manually clicking the "Get Preview Builds" option to check for new content in order to receive updates, or will I be notified automatically in due course? Is there anything else I need to do to make sure I receive the updates? (Lumia 1520, Denim, United Kingdom, Three UK)
