Hi, Codeforces! :)
I'm glad to say that IOI 2017 will begin officially tomorrow in Tehran, Iran!
During the event, we try our best to keep you updated with the news and medias and you can follow them on these channels:

• The official site
  
• Facebook page (there's also a facebook group linked to the page)
  
• Twitter page
  
• Instagram page
  
• Youtube page
  

And of course Codeforces, as a great community of relevant people!
So I invite participants to share their experience of the event here with #ioi2017iran.

Best of luck! :)
UPD1: Live coverage of the opening ceremony is now available at our Instagram and Facebook pages!
