Here are just some points to note when making changes to the .gitgnore file to ensure Git is always tracking the right files.

1. Make changes in .gitignore file.
2. Run git rm -r --cached . command.
3. Run git add . command
4. git commit -m "Commit message" or just git commit or continue working.

What is really important here is step 2. And remember to just run git add . command before doing any commit.
