The International is a huge event, and it can be hard keeping track of all the games going on. However, I discovered a massive guide to the entire event on Reddit which should prove helpful to anyone wanting to catch some games. It includes a schedule for every time zone, links to all the different streams in multiple languages, and an overview of how the entire event is set up. You can look up players, go to the sites covering the day-to-day surprises, and easily make sure you don't miss anything for what is sure to be an incredible tournament.
For those who do not know, the International is an annual electronic sports Dota 2 championship tournament hosted by Valve Corporation, the video game developer behind Dota 2. (from Wikipedia)
