At 6pm this evening UK time Apple will be announcing a bunch of new products on stage in San Francisco. We're pretty much certain that this is going to be the iPhone 6S and iPhone 6S Plus - upgrades to last year's models, as well as perhaps a brand new Apple TV.
Helpfully for those of us not in the conference hall the company is living streaming it too. Here's how you can tune in.
How to watch on iPhone/iPad
Simply point your Safari web browser at Apple's event website, or even just apple.com if you navigate there at 6pm tonight, when the video embed will probably be on the main page.
To watch the stream you'll have to be running iOS7 or later.
How to watch on Mac or Windows
If you have a Mac you can watch it in browser on Apple's event website but remember to use Safari rather than any other browser. Usually with these keynotes Apple prevents users of Chrome and Firefox to see the live stream, so you'll have to use Apple's own browser.
If you have a Windows machine the good news is that the live stream will apparently work in Microsoft's new Edge browser.
If you really want to use Chrome or Firefox, then you could try this potentially unreliable Ustream link. This is an unofficial stream that will be rebroadcasting Apple's feed - so it could depend on how nice Apple is feeling on whether the stream will work okay.
If you have VLC Media Player, which is available for both Windows and Mac (as well as Linux and Android), you can apparently also paste this URL into "open network stream". It isn't working right now, but the nerds claim that it will be working tonight:
How to watch on Apple TV
If you have what is soon to be known as "the old Apple TV", then if just before kick-off time you head into the "Apple Event" app on the device there will be an option to watch the stream live. It's as simple as that!
