To resolve merge conflicts in Git, follow these steps:
1. Identify the files with conflicts by running `git status`.
2. Open the conflicted files in a text editor. Look for conflict markers (`<<<<<<<`, `=======`, `>>>>>>>`).
3. Manually edit the file to resolve the conflicts by choosing which changes to keep or combining them.
4. After resolving, save the file.
5. Stage the resolved files using `git add <filename>`.
6. Complete the merge by committing the changes with `git commit`.
