Check your current status before changing branches.
Create and switch to a branch with a clear name.
Make one type of change on that branch.
Commit your work when it runs.
Switch back to main only after committing or stashing your changes.

Example

Conflict example

You may see a file like this after a merge conflict. The top part is from your current branch. The bottom part is from the branch being merged.

Edit it into the final version you want. Do not leave the marker lines in the file.

<<<<<<< HEAD
const title = "Campus Expense Tracker";
=======
const title = "Student Budget Tracker";
>>>>>>> feature/add-expense-form

# final file could be:
const title = "Student Budget Tracker";

# then finish the merge
git add src/config.js
git commit
