I would like to ask you for the help with these sentences including an expression "for example":
Facts about football for example are, that the first rules of football were written in 1848 at Cambridge University in UK. or
Some competitions in football for example are World Cup, Championships, Olympic games and other.

I doubt they are correct. But I want to be sure.
I would say: We know many facts about football. For example, the first rules of football were written in 1848 at Cambridge University in UK.
There are many competitions in football, for example, World Cup, Championships, Olympic games and other.


Both sentences are from a description of sport.
Thank you very much.
