+## Useful knowledge from stackoverflow
+# Even if you haven't tracked the files so far, git seems to be able to "know" about them even after you add them to .gitignore.
+# WARNING: First commit your current changes, or you will lose them.
+# Then run the following commands from the top folder of your git repo:
+# git rm -r --cached .
+# git add .
+# git commit -m "fixed untracked files"
