contribution volunteer

hi 

I a very positive about Una project and I  like to contribute in una development project, let say starting with translation and then we will se what I can do more, 

I found some pages as toturial, but they are for very old dolphin versions, is there any link to guid me to the right direction, 

for ex. how can I translate or make a group or be part of a group for such small sub project. 

just let's expand it together. cheers
