Apple today began decorating the Bill Graham Civic Auditorium in San Francisco, which is where the Worldwide Developers Conference keynote will be held on Monday. Crews have started putting up window decorations, and rainbow-colored flags, and as the weekend progresses, we should see additional banners and signage.

This year's Worldwide Developers Conference website, app, and media invites have all featured a simple but colorful dark theme, and it's likely signs and banners will adopt the same aesthetic.

Decorations have not yet started going up at the Moscone Center, where the rest of the conference will take place. Apple typically starts decorating Moscone West on Tuesday or Wednesday during the week ahead of WWDC, but an event that took place at the venue through Thursday may delay decorations until later today.

This year's keynote event will feature the debut of iOS 10 and OS X 10.12, along with new versions of watchOS and tvOS. We may hear more details on Apple's App Store changes, and we could see updates to some services, like Apple Pay. For full details on what to expect, make sure to check out our WWDC roundup

Apple will provide a live stream of the WWDC keynote on the Apple TV and on iOS and Mac devices through its website. MacRumors will also provide live coverage of the event for those unable to watch, both on MacRumors.com and through our MacRumors Live Twitter account.
