Open Stack

Greetings all,
I'm looking to gain some understanding of the CI infrastructure and 
thought it might help if I worked on a few junior bugs as a goal. I was 
wondering if there were any particular issues that people could suggest 
as a good starting point. Zuul looked like an interesting project as I 
am fan of Git;  If anyone has any particular gripes then I'm happy to 
head in the direction if you're willing to offer some assistance when 
you have the time.

Kind regards
Andrew
