What does the two numbers in the Github column mean?

Question

An example .

On this page for each contributor there is a text description, for example:

fengyuanchen 54 commits/53,994 ++/39,917 --

What do two numbers mean 53,994 ++/39,917 --and signs ++, --mean? I could not find any advice in github help or google.

I suppose they are a bit of a stackoverflow reputation mess, I was wondering how to achieve such a reputation on github, what are the rules?

Answer 1

No , the reputation of meachanism.

53,994 ++green indicates the current user-added rows and 39,917 --red indicates that the current user is deleting or replacing rows.
