A list of docs and specs in the making for someone to quickly be able to contribute

I'm not sure if something like that exists already or not, but I couldn't find it.

If I go to github.com/aerogear I see a bunch of projects, and I don't know where to start. All I really want is to join the dialogue on the features being discussed, and designed. In that sense I'm interested in where 'the action' is ATM. I imagine either a list of JIRA issues, but even those can get confusing so even better probably would be just a list of links to spec proposals, specific conversations in ML archives or IRC logs ...

A few links ... Something to quickly get me up-to-date with what's going on.
