gitlab gitignore not working code example

Example: gitlab gitignore not working

#The files/folder in your version control will not just delete themselves just 
#because you added them to the .gitignore. They are already in the repository 
#and you have to remove them. You can just do that with this:

#Remember to commit everything you've changed before you do this!

git rm -rf --cached .  # don't forget the period on the end
git add .
