Resolving merge conflicts in Git ☁️ can be done using a text editor and Git commands. Here are the steps:

1. Identify the Conflict:
When you encounter a merge conflict, Git will mark the conflicting lines in your files.
Open the conflicted file in your favorite text editor (e.g., Visual Studio Code).

2. Review the Conflict:
➡️Look for conflict markers in the file:

<<<<<<< HEAD: This shows the changes from the base or HEAD branch.
=======: Separates your changes from the other branch's changes.
>>>>>>> BRANCH-NAME: Displays the changes from the other branch.

Decide which changes to keep or modify.

3. Resolve the Conflict:
Edit the file to incorporate the desired changes.
Remove the conflict markers (<<<<<<<, =======, and >>>>>>>).
Save the file.

4. Stage the Changes:
Use the following command to stage the resolved changes:

git add FILENAME

5. Commit the Changes:
Create a new commit with the resolved conflict:

git commit -m "Resolved merge conflict"

That's it! You've successfully resolved the merge conflict. For more details, you can refer to the GitHub Docs or other resources[1]. Let me know if you need further assistance! 🚀
