Here I'll mention how I resolve GitHub Conflicts. I'm sure there are much easier and better methods to do so, but this is just for me to remember how I have done it for my future reference, and you too can use it.
A Pull Request that you have created might have conflicts or someone has made a Pull Request to your repository that has conflicts. To resolve these conflicts you can either use the web GitHub UI and resolve those Conflicts or use the command line. In some cases when the GitHub web UI is not an option and you are compelled to use the command line.
If you have to use your command line to resolve these merge conflicts you'll need a terminal. This terminal must be connected to your relevant GitHub repository.
