I added a git resource to the resource and an article that helps beginners navigate open-source contributions.

Hi there I am learning to use GitHub for contributing to Open Source projects, would the resources you shared help me to be good at this?

Hi there, In my opinion you could have just added the resources as Additional Resources without removing the previous written articles.

Looks good to me! Thanks for adding these resources ✨

Sorry for the late response. Yes the resource would be very useful!

Thank you @erictleung for accepting my PR to the repo. I hope to do more and help people remove any barrier that stops them from open source contributions.

I have also submitted an issue (#879),yet to be accepted, that aims at translating the readme file to pidgin to help people in Non-English African speaking countries that are conversant with Pidgin English easily start open source contributions.
