First off, thank you for considering contributing to GitHubUpgrade.com! It's people like you that make GitHubUpgrade.com such a great tool for developers around the world.
If you've noticed a bug or have a feature request, make one! It's generally best if you get confirmation of your bug or approval for your feature request this way before starting to code.
If this is something you think you can fix, then fork GitHubUpgrade.com and create a branch with a descriptive name.
A good branch name would be (where issue #325 is the ticket you're working on):
git checkout -b 325-add-dark-mode
Make sure you're using the latest versions of Node and npm. Install the dependencies:
npm install
At this point, you're ready to make your changes! Feel free to ask for help; everyone is a beginner at first.
At this point, you should switch back to your main branch and make sure it's up to date with GitHubUpgrade.com's main branch:
git remote add upstream https://github.com/SIMARSINGHRAYAT/APP_Commit.git
git checkout main
git pull upstream main
Then update your feature branch from your local copy of main, and push it!
git checkout 325-add-dark-mode
git rebase main
git push --set-upstream origin 325-add-dark-mode
Finally, go to GitHub and make a Pull Request!
