What are the main sources I need for Cydia?

So I jailbroke my phone and I did it before with another Iphone I previous had but everytime I go to add a source it says it about being unstable and illegal? So what are the sources I need for cydia, like the sources that give me WinterBoard or the BytaFont?

Go to google and ask the experts
