Link external app like facebook and Linkedin

Hi there, I am new in Blockstack and I am not a developer so the way everything is explained is very difficult for me to understand. I have install the newest version and some app are already intalled. I want to link Facebook and Linkedin to Blockstack but I do ot know how to do it it says it is unverified. Is there any tutorial for not developers? I get lost in every single step I try to make. Can you help?

Have you downloaded and installed the latest Blockstack Browser?
Are you still having troubles?
