When is the next build challenge

Marksets

So, recently I have come to know more about the stellar platform and all is goodness. I really want to be part of the platform and I am building a solution with the stellar architecture.

I heard of the Stellar Build challenge and I want to be part of it.
So my questions are

When is the next stellar build challenge and what do I need to do to be successful in the challenge...

Thanks guys.
