Add Linkedin ITA FRA SRB + further work

[Seandebasti]

Hi, I identified three groups on Linkedin at least.
I would like to add them myself to find a start in contributing to this project on Github. I often find some objects, I like to add, but I never started. Now, I like to begin.
Could you show me the JSON file for the only listed Chile Linkedin group, that I understand the structure. Thanks
After I probably have to do a Pull request - on which branch do I do that?
