Hi Dario, Welcome!
Have you had the chance to look through our getting started guide? [1]
You'll need fped & kicad installed to start contributing, but we also
have some pdf's of our components, schematics and footprints available
for review [2]
Currently, we still have a few ecn's to properly close [3], and need to
finish drawing and reviewing footprints [4].
Shout if you have any questions.
All the best,
Dave
