I have merged this PR exceptionally because I am curious if the contributors list gets updated. @SDBowen would be contributor number 93
I see that @amers185 has not been added after merging #3644 (although I see the commit in #3644 is from unknown user Usama.

[luisramos0]

yeah, so @SDBowen has gone into the list of contributors but @amers185 has not, probably because the way @amers185 has configured git locally the commit got a different user that doesn't match the GH user.

@luisramos0 Hello Luis! What can I do correctly on my end to go on the list of contributors? I was working on the branch created by @kevinchristianson perhaps that has something to do with it? I have also cloned openfoodnetwork but I had trouble bringing it up to date because of insufficient permissions. So I decided to work on the branch created by @kevinchristianson

[luisramos0]

it's not a problem with the branch, it's the commit itself.
something to do with your configuration of git.
maybe just this: https://help.github.com/en/articles/why-are-my-commits-linked-to-the-wrong-user#commits-are-linked-to-another-user

[amers185]

@luisramos0 Thank you for pointing me to a solution. I have made the requisite changes. Perhaps, I should have mentioned earlier but my name is Usama so that is in fact me.

[luisramos0]

yeah, I got that it was you. It's probably your local account. Good luck with that, let us know on slack if you need help.
