If you registered for a general admission or academic ticket for Google I/O 2016 last week, now's the time to check your email. Google has begun sending out the first wave of invites for the annual developer event, which runs from May 18-20 in Mountain View, Calif.

The invite email reads:

Congrats! You've been selected to purchase a General Admission ticket for Google I/O'16.

Google I/O is a festival for developers and technologists. During I/O, you'll learn about our latest product innovations and dive deep into code, all while networking with your peers and Google engineers.

And that will likely mean a lot more info about Android N, which was released in developer preview form last week.

Lucky invitees will have just 24 hours to claim their spot at I/O, during which they'll need to pony up the $900 required for a general admission ticket, or $300 for an academic pass.

In previous years Google has sent out I/O invites in waves, so if you haven't yet received yours, fear not, it may still be coming. When all the GA and academic spots are taken, unsuccessful applicants will begin receiving the dreaded I/O rejection email.

If you can't be in Mountain View for this year's Google I/O, we'll be there to bring you full coverage of everything Google announces.

Have you received your I/O invite, or are you still waiting? Shout out in the comments!
