How to exclude a folder in .gitignore on github?

Question

GitHub

Created a repository on PC. I registered the idea folder in .gitignore,

then I created a repository on the github, I make a commit and merge

the idea folder was created. And the old commits (7 pieces) all pulled up (deleted the repository from the github and created it again). My head is already boiling - either the folder was flooded there because of old commits,
or not. How to do something right?

Answer 1

Just add / at the end
.idea/
