Hello Esteban :)
Greetings, and welcome to the Fedora Design mailing list! We're happy to have you here with us. I very recently joined Fedora design team and have found the community nothing but helpful and amazing!
I do not have much experience getting people started, but thought will drop a few links for you to check until someone more experienced helps you start contributing!
There is interesting work going on in Fedora and Hubs as I have been trying to keep up. I
f you are interested, you can check out the mailing list specifically for Hubs too:https://lists.fedoraproject.org/admin/lists/hubs-devel@lists.fedoraproject.orgFedora has a very unique and interesting way to encourage contributions called Fedora Badges. They are like the virtual badges you can earn while contributing. You can learn a little more about them at this page:Justin will be the right person to get you started with this. I am hoping he will reply to this once he is free.
That's all the links that I could think of now which I bookmarked initially. I am sure someone will help you out better if you stick around. You can also hang around on IRC channel.
Thanks for sending your introduction here on the list! Again, welcome to the Design Team. :)
